<p>The function <strong>hypergeom([2/3,2/3,2/3],[-1/3,4/3],z)</strong> has radius of convergence 1 and real coefficients.</p>
<p>But Maple tells me <strong>evalf(hypergeom([2/3, 2/3, 2/3], [-1/3, 4/3], 99/100),50);</strong></p>
<p>is <strong>-138.999 + 0.0012 I</strong><br><br></p>
<p><strong><br></strong>It should be more like −138.9962313171333091754979138344422738025</p>

<p>The GroupTheory package in Maple includes facilities for working with finitely presented groups - groups defined by finitely many generators and defining relations. We now have a <a href="https://www.youtube.com/watch?v=Kph67ao9-qg%20">video tutorial</a> that covers the basics of this aspect of the package. As always, we appreciate feedback and suggestions regarding this feature, or new features that you would like to see in the GroupTheory package.</p>

<p>Maple 2015 has a new command, dataplot, for plotting datasets. It was designed to be easy to use and it offers several new features that are not available in Maple's other plotting commands. A few months ago, I recorded a <a href="https://www.youtube.com/watch?v=ATMyC6GOOdM">video</a> that gives an overview of the command. If you have any questions or comments about dataplot, feel free to post here. I'm also including the worksheet that is shown in the video: <a href="/view.aspx?sf=201263_post/DataplotWebinar.mw">DataplotWebinar.mw</a></p>

http://www.mapleprimes.com/posts/201262-Code-Generation-For-R?ref=Feed:MaplePrimes:Tagged With maple
<p>Maple’s Code Generation makes it possible to translate your Maple code to various other programming languages including <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/C">C</a>, <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/Python">Python</a>, and several <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration">others</a>. In Maple 2015, we added a new Code Generation target to one of my other personal favourite languages, <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/R">R</a>. <a href="https://www.r-project.org/">R</a> is a programming language designed for statistical computing and graphics, so no code translation from Maple to R would be complete without attempting to translate as many commands as possible from Maple’s <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=Statistics/Commands">Statistics</a> package. </p>
<p>Translating code from one language to another is tricky business. Maple 2015 represented the first time that any Code Generation target language added the ability to translate commands from the Statistics package. With R, we found that many common statistics commands had almost a one-to-one mapping, such as Statistics:-Mean = mean, but several others were much more complicated, including several commands for dealing with probability functions that did not have direct mappings due to differences in how the systems handle symbolic probability functions.</p>
<p>A list of statistics commands that can be translated from Maple to R can be found <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration%2fGeneral%2fRDetails">here</a>.</p>
<p>In addition to assisting me recall the correct syntax in R, having worked with CodeGeneration[R] for several months now, I find that one of my most common uses for Maple’s code generation to R is simply to pass data between the systems. A simple example:</p>
<pre> CodeGeneration:-R( LinearAlgebra:-RandomMatrix( 5, 2 ) );</pre>
<p>translates to the following in R:</p>
<pre> cg <- matrix(c(-4,27,8,69,99,29,44,92,-31,67),nrow=5,ncol=2)</pre>
<p>To see a couple more short examples, here’s a short video that I recorded on Code Generation to R: <a href="https://www.youtube.com/watch?v=0Mn1W2j56aA">https://www.youtube.com/watch?v=0Mn1W2j56aA</a></p>
<p> </p>
<p>A little known fact about Code Generation is that the translation files can be viewed in from the “samples” directory in your Maple install directory. Similar to many of Maple’s packages, you can view all of the source code that Code Generation uses for its translations. For example, you can view the translations for the commands that I mentioned above from the “FunctionTable.mm” file inside of your “%MapleInstallDir%/ samples/CodeGeneration/R” directory.</p>
<p>Should you have any feedback on this translation, or any other, please feel free to contact us. We’re also on the hunt for our next code generation targets, so let us know what other languages you would like to see added as Code Generation targets.</p><p>Maple’s Code Generation makes it possible to translate your Maple code to various other programming languages including <a title="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/C" href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/C">C</a>, <a title="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/Python" href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration/Python">Python</a>, and several <a title="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration" href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=CodeGeneration">others</a>.

http://www.mapleprimes.com/questions/205347-Why-Does-813-Become-1Complex1?ref=Feed:MaplePrimes:Tagged With maple
<p>Hello people in mapleprimes,</p>
<p>I have a question about why what is shown by maple by simplify(-8)^(1/3) is 1+ Complex(1)* (3)^(1/2)?</p>
<p>Solutions of x^3=-8 are -2, 1+Complex(1)*(3)^(1/2) and 1- Complex(1)*(3)^(1/2). And, as for the last one, 1- Complex(1)*(3)^(1/2), it is </p>
<p>the conjugate of the second, so it might not need to be written, because of it being easily seen so.</p>
<p>Is it the same reason why just -2 is not shown as the result of simplify((-8)^(1/3))?</p>
<p>PS. I know the instruction to use surd in such a case.</p>
<p>the reason I asked this question is this:</p>
<p>I am reading Essential Maple, where</p>
<p>ln(z) = ln(rho*exp(Complex(1)*theta));</p>
<p>ln(rho*exp(Complex(1)*theta))=ln(rho)+Complex(1)*theta;</p>
<p>ln(rho)+Complex(1)*theta;=ln(rho)+Complex(1)*arctan(y,x);</p>
<p>and</p>
<p>z^a=exp(a*ln(z));</p>
<p>and</p>
<p>"Because of</p>
<p>exp(w*Pi*Complex(1)*k)=cos(2*Pi*k) + Complex(1)*sin(2*Pi*k);</p>
<p>and</p>
<p>cos(2*Pi*k) + Complex(1)*sin(2*Pi*k)=1;</p>
<p>we could equally well have chosen</p>
<p>ln_k z = ln(z) + 2*Pi*Complex(1)*k"</p>
<p>are written.</p>
<p> Supposing these, there is a sentence that</p>
<p>"we choose k=0, and thus -Pi<=theta<=Pi to be the one (that for our canonical logarithm).</p>
<p>Every computer algebra language and numerical language follows this standard and takes the</p>
<p>complex logarithm to have its imaginary part in this range.</p>
<p>With this definition, (-8)^(1/3)=1 + Complex(1)*sqrt(3), and not -2. (the end of quotation)"</p>
<p> </p>
<p>And, I can't understand the last sentence"With this definition", so I asked the above question.</p>
<p> </p>
<p>I hope someone give an answer to the above question.</p>
<p> </p>
<p>Thanks in advance.</p>

<p>Hello all ,</p>
<p>Having read a recent post about comparing Maple and Mathematica I'd like to throw my 2 cents (FWIW).</p>
<p>It is *silly* (not to say stupid) to compare these two softwares.</p>
<p>Maple can do "things" that Mathematica can't. For examples Differential Geometry, Lie Algrebra, covariant derivative and the like.</p>
<p>And Mathematica Manipulate command is far better than Maple Explore (just another exemple).</p>
<p>I have being using Maple since Release V.2 (1992) and Mathematica since Release 1.1.a (1991).</p>
<p>I use both of them on a daily basis and I *LOVE* them both.</p>
<p>Inputs are welcome :-)</p>
<p>Kind regards to all,</p>
<p>Jean-Michel.</p>

http://www.mapleprimes.com/questions/205162-How-To-Write-A-Recursive-Function-With?ref=Feed:MaplePrimes:Tagged With maple
<p>Dear All,</p>
<p>I am new to maple and trying to write a recursive function with two input variables, but when i execute the statement it shows error "Error, (in B) too many levels of recursion"</p>
<p>Following is the set of instructions which i am trying to execute:</p>
<p><strong>if n=1 then </strong></p>
<p><strong>B(m,n):=omega(m); </strong></p>
<p><strong>else </strong></p>
<p><strong>B(m,n):=sum(omega(j)*B(m-j,n-1),j=1..m-1)</strong></p>
<p><strong>end if</strong></p>
<p><strong><br></strong>After execution, i try to access B(1,1) or B(2,1), the following error occurs</p>
<p><em><strong>B(1, 1);</strong></em><br><em><strong>Error, (in B) too many levels of recursion</strong></em></p>
<p><strong><br></strong>I'll be grateful, if someone can help me to fix this problem. </p><p>Dear All,</p>

<p>I created my own package and one procudure inside this package is to calculate the eigenvalues of a identity matrix, as shown below</p>
<p><img src="/view.aspx?sf=205156_question/packageSource.jpg" alt=""></p>
<p> </p>
<p> </p>
<p> </p>
<p>Then, I use this package in another document, all other procedures work well except the procedure calculating egigenvalues, as shown below</p>
