[Help-gsl] accessing matrix dimensions?

[Waclaw Kusnierczyk]

Hello,

I need to write a generic function to perform operations on matrices.  
The matrices passed as arguments may be of arbitrary dimensions, so I 
need my procedure to get the dimensions somehow, best directly from the 
matrix object (as the information is stored there already).

I can't find appropriate routines in the interface -- I'm thinking about 
something like

    int nrows = gsl_matrix_size1(const gsl_matrix *m);

It's possible to write code like

    int nrows = m->size1;

but I'd prefer to avoid breaking the abstraction barrier.

Regards,
vQ
