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@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
