How can I tell Maple to compute the product of tow symbolic matrices

A:=Matrix(2, [[a,b],[c,d]]);
B:=Matrix(2, [[e,f],[g,h]]);

C:=multiply(A,B);

to have C:=([ae+bg, af+bh],[...])

Hi im somehow not able to export my worksheet into a word document, as the rtf format doesnt seem to be available on the maple 15 mac version. converting into html is possible but not satisfying. i really need help here.

thanks a lot !!!!

greetings

What is the distance between the trigonometrical polynomials of the form a0/2+a1*cos(Pi*x)+b1*sin(Pi*x) and the polynomials of  degree at most 1, ie c0+c1*x, in the Chebyshev metrics on the interval [-1,1] and in the L^2 metrics on the same interval?

i want '*' to keep doing exactly what it already does. for example, x*x*x*x is still x^4.

but furthermore, i want to be able to somehow redefine(define in addition) '*' as follows:

protect('a');protect('b');

redefine('*', a*b=1,b*a=-1);

basically, for protected letters a and b, maple...

How can I plot f(x,y)=(cos(x^2+y^2))^1/2 whithout knowing the domain?

And then having Maple to find the domain and plot it?

Thanks.

I have a package, a zip file, written by someone, it consists three files, as seen below

what this package, let's call it helloworld, offers is the following:

all i need to do is extract those three files shown (hdb, ind, lib) into C:\Program Files (x86)\Maple 12\lib

then once i type with(helloworld):

1, it modifies the...

hi

i want to solve following equation

f(s)=a+b*s+c*s^2

with these condition

f(0)=0

f'(0)=0

f'(5)=1

please help me

thancks

hi,

please Help me in the following code :

I have a set of nonlinear and coupled PDEs for a cable actuated system. I want to transfer this set to a set of ODEs and write it down in Matrix form. I used Galerkin's method and derived the ODEs in discritized form. I have a problem in converting this set of equation into a matrix form like "Mq"+Cq'+Kq=F". The derived equations are very complicated and contains some nonlinear terms. One of the three equations looks like this:

i want to create my own package Helloworld (includes proc1 and proc2) so that people can do

with(Helloworld);

and get

[proc1,proc2]

and then they can then use proc1 and proc2 as they wish.

thanks in advance

Hi

When the numerator of a quotient is a negative integer, Maple puts the quotient into parentheses and the negative sign before the quotient (not with the numerator). Here is an example:

with(RandomTools);
a1 := Generate(integer(range = -10 .. -1));
Limit(a1/(x-3), x = 3, right);

I would like to have the negative sign with the numerator and to remove the parentheses.

I tried to export the limit in MathML, but it didn't work.

hi,

i want to solve this equation :

f(n+1)(x)=f(n)(x)-int [ (s-x)^2 * ( F"(n)(s)+.5*F(n)(s) ) ds]

 integration is from  -infinity  to  x

with this initial guess   f(0)(x)=A+Bx+C*exp[-x]

i want for example F(4)(x) in terms of A,B,C

 and then calculate A,B and C with this condition

f(0)(4)=0

f'(0)(4)=0

f'(10)(4)=1

please help me

thancks

Dear guys

I have an expression and I solve it by "solve". It has two results and I want to choose first of them. How can I choose for example the first result? Is the order of results the same if I run the program many times?
