I Need to Generate Primitive and Irreducible Polynomials in Galois Extension Field GF(2^32). How do I do it? Any Pointers to any code / theory is welcome. Thanks
I want to 'revert' the product rule from differentiation: I want to collect terms like f(x)*diff(g(x),x)+g(x)*diff(f(x),x) into diff(f(x)*g(x),x)
I'm having problems using Compiler:-Compile() on the following procedure: findallroots:=proc(eqs,x,rng::range(numeric)) local roots,pts,i; roots:={fsolve}(eqs,x,rng,'avoid'={x=lhs(rng),x=rhs(rng)}); if roots={} or not roots::set(numeric) then NULL else pts:=sort([op(rng),op(roots)]); op(roots),seq(procname(eqs,x,pts[i-1]..pts[i]),i=2..nops(pts)) end if; Error, (in IssueError) only named functions are supported If you could help me with what this error is referring to and what I could do to over come it that would be most appreciated. Thank you for your help
I am a novice in using maple-matlab link. I followed the help manuel instruction in maple, as below. The command "with(Matlab);" executed successfully. And I found new Matlab command window activated. Even openlink() executed without error. But I can't use any matlab command in maple due to link lost error below. My maple version is 8.00. And my matlab version is 6.5.0. I will be very grateful for anyone's help. > restart; > with(Matlab); [chol, closelink, defined, det, dimensions, eig, evalM, fft, getvar,inv, lu, ode45, openlink, qr, setvar, size, square, transpose] > > A:=matrix(2,2,[1, 1, 1, 2]);
Here is a simple Maplet example,
This topic was developed in a discussion with Mad Math. In Maple, pattern based transforms can be done using following Subs procedure
Here are the steps for making StartMaple example with Dev-C++.
  1. Start Dev-C++.
  2. Click File - New - Project, select Console Application, check C Project radio button and type the name of the project - something like SMexample.
  3. Copy the source from ?StartMaple help page and paste it in main.c (instead of pretyped text there).
  4. Click Alt+P (or Project - Project Options), go to Directories, select Include Directories and add C:\Program Files\Maple 10\extern\include there.
  5. In Parameters (in Project Options) in the Compiler window type -D_MSC_VER and in the Linker window click Add Library or Object and add "../Program Files/Maple 10/bin.win/maplec.lib" .
I am trying to invoke Maple from a C program, using OpenMaple, copying the Maple help screen example (see StartMaple). I've of course changed the path to the header file. However, I get a linker error: 'StartMaple is an unrecognized function'. I take this to mean that the .lib and or .dll maplec files are not being linked in, but I can't seem to figure out how to. I'm using Dev-C++ as the compiler. Anyone have experience with this
Is there a straightforward procedure to have a radical appear on the plot of a function? E.g, how can one display (2, sqrt(2)) in the plot but with the actual square-root symbol appearing. I've read in the knowledge base about the use of textplot. However, the routine is limited to exponents.
I want to plot the volume that is enclosed by the following four areas: x^2+3*y^2=z z=0 y^2=x x^2=y I got so far that my plot looks like this .
eqn :=-p*(l^2-a^2)^(3/2)+a^3*q; l is letter not number if want to find a .....a =??......plz use maple to find the answer i use hand to do it, so the answer is a = (p^(1/3)*l)/sqrt(p^(2/3)+q^(2/3)); but i use Maple it gave me different answer.... so plz help!

This is a program discribing the dynamic behavior of a N pendelum system. When I tried to comparae the result of different initial conditions, I found that every time i run it, the graph will be different.

I know that double pendelum system is a typical chaotic system, is this the reason why i have different result for each time?

Here I attach the file, but plz rename it to ***.mws file before run, b/c i wrote it in maple classic worksheet.

I'm having difficulties in using the Heaviside function in Maple. My heaviside function is (t-tau), and I'm having trouble integrating tau from zero to t. After integration, the expression still shows an integral. Is it because when tau = t, the heaviside becomes zero? Any and all help is appreciated. Attached is the actual sheet. The 2nd to last and last steps are the steps or concern.... **** This problem has been overcome *****
How do use an equation to create a list/array?

e.g y=x*5+1

for x from 0 to 1 in increments of 0.1

answer should look similar to:
[0,1]
[0.1,1.5]
[0.2,2]
[0.3,2.5]

Has anyone been able to use the statopts option in the Bootstrap command which is in the Statistics package in Maple 10? Note the following sequence of commands > with(Statistics) > Bootstrap('Mean', [1, 2, 3, 4, 5], replications = 6, output = array) print(Matrix(1, 6, {(1, 1) = 2., (1, 2) = 3.39999999999999990, (1, 3) = 2.20000000000000016, (1, 4) = 2.79999999999999982, (1, 5) = 3.60000000000000008, (1, 6) = 2.20000000000000016})); [2., 3.39999999999999990, 2.20000000000000016, 2.79999999999999982, 3.60000000000000008, 2.20000000000000016] According to the documentation which is attached as a PDF file it appears that this command should work.
