Data structures are sort of foundational, shouldn't we discuss them also
now?
I'd like to know how the developers of GSL ended up using gsl_block
within gsl_vector and gsl_matrix. Why is it needed?
tda in gsl_matrix struct is a bit of a mystery to me, what is it used for?
I agree that use of other libraries and even other languages with GSL
should be made as easy as possible. Data structures with dimension > 1
should be explicit about the data being stored as "column-major" or
"row-major".
