Heun functions in Maple
http://www.mapleprimes.com/questions/203384-Heun-Functions-In-Maple?ref=Feed:MaplePrimes:New Questions
<p>At the internet site of The Heun Project, a strong declaration is made that only Maple incorporates Heun functions, which arise in the solution of differential equations that are extremely important in physics, such as the solution of Schroedinger's equation for the hydrogen atom. Indeed solutions appear in Heun functions, which are highly obscure and complicated to use because of their five or six arguments, but when one tries to convert them to another function, nothing seems to work. For instance, if one inquires of FunctionAdvisor(display, HeunG), the resulting list contains</p>
<p>"The location of the "branch cuts" for HeunG are [sic, is] unknown ..." followed by several other "unknown" and an "unable". Such a solution of a differential equation is hollow.</p>
<p>Incidentally, Maple's treatment of integral equations is very weak -- only linear equations with simple solutions, although procedures by David Stoutemyer from 40 years ago are available to enhance this capability.</p>
<p>When can we expect these aspects of Maple to work properly, for applications in physics?</p><p>At the internet site of The Heun Project, a strong declaration is made that only Maple incorporates Heun functions, which arise in the solution of differential equations that are extremely important in physics, such as the solution of Schroedinger's equation for the hydrogen atom.

http://www.mapleprimes.com/questions/203381-Mixing-Computed-Values-And-written-Math?ref=Feed:MaplePrimes:New Questions
<p>Dear Maple users</p>
<p>I have a question which is maybe easily solved, but I cannot seem to find the solution myself. A vector X of coefficients has been computed earlier in the Maple document and I want these coefficients placed in front of some written symbols in order to make Maple display the final result in a nice way. I made an attempt with the Vector command as shown in the image, but I cannot make the indices start at -2. In addition I want some written math placed in front of the expression. In fact I want it displayed like shown on the image marked with a red rectangle. I did write this manually, but want Maple to do it automatically when given the coefficients vector calculated earlier. I hope someone can help me here!</p>
<p>(It is about finite difference methods, by the way)</p>

<p>Hello people in Mapleprimes,</p>
<p> </p>
<p>I wish you to teach me about this.</p>

<p> </p>
<p>pt3 := Matrix(4, 2, [1, 3, 4, 5, 6, 8, 5, 10]);</p>
<p> </p>

<p> "==",</p>
<p> "(", convert(pt3[2, 1], string), ",", convert(pt3[2, 2], string), ",", ")",</p>
<p> "==",</p>
<p> "(", convert(pt3[3, 1], string), ",", convert(pt3[3, 2], string), ",", ")",</p>
<p> "==",</p>
<p> "(", convert(pt3[4, 1], string), ",", convert(pt3[4, 2], string), ")"</p>
<p>)</p>
<p> </p>
<p>The above code makes </p>
<p>string1 := "(1,3,)==(4,5,)==(6,8,)==(5,10)"</p>
<p> </p>
<p>What I want to know is how to write a code of programming without writing each row of the above code.</p>
<p>Actually, though I wrote 4 row matrix above, the number of rows of matrix I want to deal with might be more than 100.</p>
<p> </p>

<p>The above code makes </p>
<p>string1 := "(1,3,)==(4,5,)==(6,8,)==(5,10)"</p>
<p> </p>
<p>What I want to know is how to write a code of programming without writing each row of the above code.</p>
<p>Actually, though I wrote 4 row matrix above, the number of rows of matrix I want to deal with might be more than 100.</p>
<p> </p>
<p>Best wishes.</p>

<p>I am new to Maple. I am working though the manual and in chapter two I tried to get the derivative of ln(x^2+1). I am getting something completely different that the actual derivative. I tried a simple derivatie (the derivative of 2x and get 0). I do not know what I am doing wrong. Any help will be appreciated.</p><p>I am new to Maple.

<p>How can I link the axes in two or more separate plots so that when I zoom in one, the others are also zoomed. Also when I want to link the 'x' or the 'y' axis only.</p>
