[Help-gsl] Fwd: Re: strange 'data' pointers using more than one submatrix simultaneously

[Matthias Sitte]

Forgot to CC the list...

An implementation-related questions: Why does gsl_matrix_submatrix()
return a view of a matrix on the stack (which just wraps the underlying
gsl_matrix struct) and not a pointer to a newly created gsl_matrix
struct (which I would have to free manually, but I have to free most of
GSL's structs by hand anyway)???

If there is no quick answer, that's fine, I was just wondering...

I have no time to look into that right now. Please always include the
mailing list in your replies - that makes it much more likely that
anyone will answer your question soon.
