Hi, I've been working with the Maple recently. And couple days ago I've just stopped, why, I don't know how to generate the C code from matrix, using the CodeGeneration with this Optimize option. But where exactly the problem is:
For example we have a matrix H:=

Hello was looking around the net for a guide to help my and then I fell over your lovely site here ;) I have a small problem, if I insert a prompt in a "Document Sheet" in Maple 10, then I can't remove it again ? The > is like rock solid, can't delete, backspace, 2nd mouse or anything to get a normal empty line back ?? Thx in advance for your help ..

Hello.
I hope someone has a trick for me:
I have the following polynomia:
>restart:with(linalg):
>g:=(x,y,z)->5*x^2+8*y^2+5*z^2-4*y*z+8*x*z+4*x*y;
My question know is how to create the following list (for use with subs, eval or similar:
>L:=x^2=5,y^2=8,z^2=5,z*y=-4,x*z=8,x*y=4;
I can offcourse just enter the list, but this is not possible when I have very large polynomias.
I tried the "coeff" and the "coeffs", but was not able to get what i wanted.
Any suggestions?

How do i show data points on spline on same graph and integrate to find the area under curve.
i have the spline and the data but cannot get them on the same graph

How do i use LSSolve to fit the correct resonance function to a set of experimental data, thanks

Hi, I want to make the following integration: R0:=int(-P_m*(-1+exp(-30*Di_d/P_m/(1-u*P_m^v+q*P_m^r)*q*P_m^r))/kappa*exp(-P_m/kappa), P_m=0..infinity) Di_d, u, v, q, r and kappa are all constants, which are all positive parameters. P_m is the only variable (so R0 is a function of P_m). As the solution of the integration Maple gives just the integral sign from 0 to infinity and the unsolved equation. Does this mean that Maple is not able to find the solution? So it is not possible to do the integration? However Maple is able to plot its solution. How is this possible? Is the plotting just an approximation?

Greeings, Can Maple write out the symbolic form of a Taylog Series? Thanks in advance, David

How do i use LSSolve in maple, i have a set of data and a formula and i need to use LSSolve to fit a curve to the data and then plot it.
thanks

HI,
I am a Masters student, engaged in research with a small applied maths component, nothing more complex than matrix calculus.
I am currently using Scilab, but would like to get a student version of one of the following:
Maple
Mathematica
Matlab
Why should I choose Maple? I'm not looking for marketing BS - I can get that off the websites, but I am looking for genuine opinions and facts from people who have more experience than me with these packagaes.

Hi All you folk with more experience than I have. Question 2. Is there a way to place the legend in a graph next to the graph rather than below it? Question 3. How can I create my own own variable names... I want to place a ˜(tilde) above a character, present task requires the ˜ above a 'v'. Question 1. This was answered unsatisfactorily in "Symbolic characters in plot titles". I have attached a worksheet with my quetsions. Any help will be appreciated :) Thank you Al

Is there an easy way to do numerical differentiation in Maple? I have a set of data, but would like to try differentiating numerically rather than fitting the data to a curve first.
Thanks

I have the function f(x,y)=(x^2+3y^2)e^-x^(2)-y^(2),
and when I try to graph it with either plot 3d or implicit plot 3d I get nothing. Ant ideas what I need to do?
Thanks!

I've compiled and run the samples\openmaple\simple\simple.c from Maple 9.5.
How do I get the program to run without displaying the spash screen? When running executables from a command line, this splash screen is annoying.
The -q (for quiet) command line arguement does not work. Other command line arguements are evaluated by the api. Give it a non-existant arguement and it gives a usage reply as expected.
The openmaple api spawns the spash screen found in bin.win\oms32.exe. Renaming this file causes an error: "Error launching OpenMaple splash screen." I can't delete the file, The error message is just as annoying as the splash screen.

I want the data returned from a Maplet Evaluate to appear in a Table. I have listed below an example Maplet:
with(Maplets[Elements]):
> setdata:=proc()
> Maplets[Tools][Set]('expdata'= [[5,42.6],[10., 31.5], [15,28.8],[20., 22.3], [30., 18.7], [45., 14.1], [60., 11.1], [90., 7.7], [120.,4.9], [180., 2.5], [240., 1.3], [300., .7]]);
> end proc:
> maplet := Maplet([
> # [BoxCell(Table([A, B], 'expdata'), 'as_needed')],
> [BoxCell(TextBox['expdata'](3..30))],
> [Button("OK", Evaluate(function='setdata()'))]
> ]):
> Maplets[Display](maplet);
The Commented out "Table" line fails and the "TextBox" works OK. Is there a way to have this data appear in Table form?

how do i use LSSolve to find least squares solution to a function and plot it. Thanks
