[GiNaC-list] symbolic matrix

[Luis Rivera]

Hello,

I have some problem accessing the elements of a symbolic matrix.
For example the code below creates a 2x2 symbolic matrix 'A'
but I can't access the individual elements.

The output I get when I run the small program below is:

[luis at urubamba ~/GiNaC]#87 ./AA
A(0,0) = [[A00,A01],[A10,A11]]
matrix::operator(): index out of range

What am I making wrong?

Thanks for any hint.

Luis
