I'm analyzing the following system: Delta[s] := phi*p*(1-exp(-n))-rho*s Delta[p] := xi*(1-exp(-s))*(Lambda-p)-p Delta[n] := mu*Lambda*p*(1-exp(-n))-omega*n I can find solutions with fsolve. Now I'd like to plot the solutions as a function of Lambda. How would I do that? I've tried using f:=Lambda->fsolve(...) without luck. Any help appreciated. [Sorry, no worksheet. File size is 40.3 kb and it looks like there is a 40 kb limit on uploads...]

Hello, I've got the following problem: I want to build a Maplet with the Maplet Builder. This Maplet shall contain a plot, a slider and a textfield. After moving the slider, the plot shall change and at the same time the textfield shall show the value of the slider. Is it possible to assign two conjunctions to the slider at the 'onchange' field? Thanks for helping, Frauke

First off I want to say thanks for answering my previous question. I'm having trouble getting maple to define an array of equal size to a given value, x, and then populate it with the numbers 0 to x. Say x was five, I would need Maple to generate [0,1,2,3,4,5]. Lastly, I need to be able to use each member of the final element individually, so I'm not even sure if I'm having Maple do this in the right manner. So far I've tried: m := proc (n) options operator, arrow; array(1 .. n) end proc; for i to n do m[i] := i end do and all I get is: Error, final value in for loop must be numeric or character.

can anybody help me in converting *.jpg to *.mws? i need to change this format as an input to an analysis software named imageMaster Viewer thank you

I'm working with inverse of a complicated matrix, which is 12*12, and all the elements are symbols. I included that matrix at the end. The program is running forever, no results, no error message? Anybody has such kind of experience, any suggestion that what I can do? Thanks a lot, I appreciate your help! Matrix([ [a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+b+c,a+b,a+b,a+c,a, a,a+c,a,a], [a+b+d+w*e,a+b+c+d+e,a+b+d+w*e,a+b,a+b+c,a+b,a,a+c,a, a,a+c, a], [a+b+d+w^2*e,a+b+d+w*e,a+b+c+d+e,a+b,a+b,a+b+c,a,a,a+c,a, a,a+c], [a+b+c,a+b,a+b,a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+c,a,a, a+c,a, a],

Hi !
I'm wanting to make an animation from images. But these images are not plots, they are lists of plots, which I display simultaneously using the display function. So I've a list of list of plots, which I want to be displayed as an animation. The syntax is animate(function_that_returns_a_plot, ...), and I can't return a plot, since a list of plots is not a plot. Does anybody know what to do ?
Thanks in advance :)

Hi, this is my first time posting, so I'm not even sure if this is the right place to ask this. But, I'm having trouble defining a function. I'm using the document view and trying to establish Q(variables)= some function and it returns "Error, invalid parameters for inline function." More specifically:

While responding to a question about creating a new type, I suggested that a module could be used as the data-structure. To type check a given expression against the new data-structure, one can use

type( some_expr, '`module`'( 'export1', 'export2' ))

where export1 and export2 are exports of the module. That technique, however, is not robust in that any module with those exports (and possibly others) matches the type. While that may not be a concern, there is a way to uniquely type check a constructed module: give it an export equal to a local value. Here is a demonstration of the technique:

I've been trying figure out how to code up arbitrary volume and surface integrals in Maple. I know that Maple has the VectorCalculus package but there doesn't appear to be a way to specify a volume integral (where the infinitesimal is dV). Also, there doesn't seem to be a way to specify a surface integral without defining the surface in advance (i.e., integrate over S with an infinitesimal of dS). In both cases, I'd like to have general integrals where I can specify the bounds at a later time (e.g., inert integrals). I know that there is the triple integrals in the student package but they aren't the same as a volume integral.

Dear all : I have a function qx(x):= 1/21 x in (20,40) = 0 others ; My double integral is like integral ( integral (qx(x1), x1=x-10..40)*integral(qx(x1),x1=x-20..40)*1/20, x = 20...30); since the qx(x)'s is not keep constant on whole range, I am confused with the double integral. Any help is appreciated. Thanks

I have two lists viz. X:=[a,b,c,d,e,f,g,h,i] of size 9. And I:=[1,2,3]. I want to generate a list of all the possible patterns of size 9 which can be made using 1,2,3. For example a few patterens which the code is to produce, among many others, are as follows: [1,1,1,2,2,2,3,3,3] [1,2,2,1,2,2,1,2,2] [2,3,3,2,3,3,2,3,3] [2,2,2,2,3,3,3,3,3] etc. Your help would be a great great help to me. I need it direly.

Hello,

Here is my problem:

> vec1:=Vector(2): plot(vec1[floor(x)], x = 1 .. 2);
Error, bad index into Vector

The above should give the zero plot, but it gives the error message.

Of course, vec1[floor(x)] gives the correct answer for any specific x. (i.e. vec1[floor(1.5324)] gives 0, which is correct).

I get the same problem when plotting or integrating functions that simliarly depend on Matrices. What's going on?

Sincerely,
Adeel

A member recently asked for a description of the mw or mws worksheet format. Click on the following link to download a pdf that I created a couple years ago that describes the syntax of the older mws format. It isn't complete, but covers most of the constructs that one is likely to need. To get a good practical understanding of the mws format, I wrote mws-mode.el, an emacs-mode that displays mws files in a structured manner. Download 84_mws-syntax.pdf

I'm looking for a method to extract the (unique) functions of a specific variable from a sum of functions, for example from u=sin(x)*sin(th)+sin(x)^2+sin(2x)+sin(th)^2+exp(x)+x i want to extract for x unique functions = {sin(x),sin(2x),exp(x),x} and for th unique functions = {sin(th)}. For a sum of only trigiometric functions, I use indets(u,trig(x)) and indets(u,trig(th)). However, for a sum of general functions I have no clue how to do this. Any help is welcome. Niels.

I had installed Maple 9.0 for linux (SUSE 10.0). When I start it, I see an error message "Connection to Kernel lost". Have someone any advice? Thanks Angela
