but matrix_range does not feature a resize(size_type,size_type).
The idea would be that you can constantly resize the adaptor
(matrix_range) as long as it is smaller or equal in size to the matrix
it originates from.

I can't find that, the constructors e.g. looks like :
NUMERICS_INLINE
matrix_range (matrix_type &data, const range &r1, const range &r2):
data_ (data), r1_ (r1), r2_ (r2) {}
