I am attempting to use document blocks to hide the Maple code for an interactive document and I'm encountering an unbelievably frustrating issue: if I create a new document block and suppress the output of the function calls therein with a colon, when I collapse the document block, the function calls are not hidden at all, but are displayed in a continuous line. If I do not supress the output, once I collapse the block, only the output is visible (which may be desirable except that I am doing things like loading packages, storing plot3d and plot variables, etc., and I DO NOT WANT THE OUTPUT VISIBLE).
I'd like to define a function f(a,b)= product(product(p(a,b,c[i],d[j])^x[ij]*(1-p(a,b,c[i],d[j]))^(1-x[ij]),j=1..n),i=1..n) (The x's are known data, each 0 or 1, the c's and d's are also known.) Is there a way to do this without writing it out long-hand, say using a matrix of the x's and vectors of the c's and d's? Thanks.
I have an array of functions involving x such that array[i] is valid only on the interval x=i..(i+1). I am trying to create a piecewise function that includes all array[i] terms valid in their respective ranges, but I am running into some syntax problems.
Hi! I am new! I can't integrate this... could u help me? (exp(-1/2*(ln(y)-(x*b+2))^2/(sigma^2*(x^2+1)))/(y*sigma*sqrt(2*Pi*(x^2+1))))*(2-1.666666667*x), x=0.6..1.2, y=3.6..4.5
Can any one of you help me to solve the question below? Please... Question: Find non-negative integers solutions that satisfy the following conditions: Given: p,k,h,a,b,c are integers. The conditions are: (1) a+b+c=k*h-h-h*h+1 (2) (p-k+h)*(p-h-1)*(p-1)-(p-k)*(p-2)*(p)=a*(p-1)+b*(p-h-1)+c*(p-k+h) (3) h>=1 (4) h
Hello All!
When using Maple 10 Classic Worksheet, the mouse sensitivity goes up tremendously, making it really annoying to work with. The sensitivity is only increased in the Maple window when it's activated. I only have this problem with Classic Worksheet, but it's the 'version' I use. Is there any workaround for this? Like some sort of registry fix?
I'm using a Logitech Mx500, by the way.
Any help is really appreciated!
Hi, I have a very problematic question. I have a Matrix (100 x 100) that contains complex numbers express as symbols. The numbers derive from several operations. I want evaluate the Real part of the complex numbers for successive calculus but the software show a memory problem. How can I do? I have a P4 with 2GB of memory. I use the function: map(Re,matrix); Thanks
Greetings! I plot a 2D standard figure in Maple 10. I select the figure, right-click it and choose "Export as". The file format I want is Encapsulated PostScript files (.eps), which is one of the alternatives. I save the figure as an .eps file in a map. Everything works fine until I import the file in Scientific Word. The figure is imported all right, but has been rotated 90 degrees counter-clockwise. I do not know how to rotate it back. I know there is a package in SW that enables rotating, but I can't get it to work. Is there something I can do in Maple to correct the problem? Is it a common problem for other users and how do you solve it?
Hello, I'm trying to make a wrapper procedure that will launch an external program with some dynamic arguments. To do this I created a proc and used the launch command from the process package. My procedure seems to be syntactically correct, but when I run it all it does is echo the procedure code. Since nothing was working I have created a simplified procedure that simply tries to launch Notepad. Instead of launching notepad it just echos out the source of the procedure: My definition of the procedure RunNotepad: > RunNotepad() := proc() > use process in > launch("notepad.exe");
Hi, It's quite easy to find the eigenvalues of a matrix, but is there a function to find the dominant eigenvalue ?
Hi I was wondering how many people are using the MapleTA Blackboard plugin? Thanks - Michael
when expanding an expression like (x+1)^7*(x-2)^9, how do arrange the terms by increasing/decreasing degree? ie ax^16+bx^15+cx^14+...
Is there a way to create periodic piecewise functions in Maple 10 for use in solving differential equations with periodic forcing functions?
I've been trying to find information about this apparently elusive (or perhaps obscure) topic without a lot of luck. I was curious if anyone had ever heard of a technique for solving an nth-order nonhomogeneous linear ODE with constant coefficients by means of Duhamel's Convolution Principle. The guy who taught this technique to me didn't believe in using textbooks (or staying in accordance with predefined curricula) and he basically just taught whatever he wanted. He essentially claimed that any nth-order nonhomogeneous linear ODE with constant coefficients could be solved by first solving the associated homogeneous equation, and then, writing a new function (he usually called it theta(t)) using the same form as the solution to the associated homogeneous equation but with initial conditions such that, for t = 0, theta of t, theta prime of t, theta double prime of t, etc., all equaled 0, except for the final condition (theta^(n-1)(t)) which equaled 1.
I have a large program I have been writing using Maple 10 classic. The heart of the prgram is a large iterative loop that spits out various data as it converges on a solution. My problem is that I would like to see certain data and suppress other output. I accordingly assign a colon and semi-colon to the respective lines. But wether Maple actually displays what I want of not seems random. The screen is flooded with unwanted interim data, and only select desired output gets through. Is there some rule with what Maple outputs if its in an iterative or nested iterative loop?
