I try to calculate a big matrix product which is used after for the resolution of a differential system.
In the link below, you have the matrix product which causes me trouble.
The matrix are composed with trigonometric functions.
I think that the problem is due to the fact that Maple tries to determine a analytical solution.
But, for my use, i only need a numerical result that i can use after for solving my differential system.
Have you some ideas in order to make this matrix product?
Thank a lot
