[Bug-gsl] reference manual error

[Gabriel Withington]

I couldn't find a place to report a typo in the manual, so this is my best 
guess. In the section "Vectors and Matrices: Matrix views" in the description 
of the function gsl_matrix_submatrix() there is the line:

m'(i,j) = m->data[(k1*m->tda + k1) + i*m->tda + j]

which I believe should be:

m'(i,j) = m->data[(k1*m->tda + k2) + i*m->tda + j]

I hope this is helpful.
