## large matrices...

Maple

As soon as my matrices are larger then 10 by 10, Maple doesn't show them. Instead I get

Vector(4, {(1) = ` 14 x 14 `*Matrix, (2) = `Data Type: `*anything, (3) = `Storage: `*rectangular, (4) = `Order: `*Fortran_order})

How can I change this?

Thanks!

## set of matrices...

Maple

How come this doesn't work:

> A := {Matrix(2, 2, {(1, 1) = 1, (1, 2) = 1, (2, 1) = 1, (2, 2) = 1}), Matrix(2, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = 0, (2, 2) = 0})};

> evalb(`in`(Matrix(2, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = 0, (2, 2) = 0}), A));

Maple answers here false. Is the in-command only for numbers and not for matrices? How can I solve this problem?

Thanks!!

## multilinear...

Maple

Hi,

I have a problem with define(f,multilinear). I want that Maple threats alpha[i,j] as a constant such that f(e[1], alpha[2, 4]*e[4])=alpha[2,4] f(e[1],e[4]). I've added all the alpha[i,j] to the constants, but still, he fails to compute f(e[1], alpha[2, 4]*e[4]).

It works when I add alpha(i,j) to the constants, but then the rest of my program doesn't work, so it really should be with [,] and not with (,).

Thanks!
