Is there any easy way to sort a gsl vector in descending order?

gsl provide APIs to sort a vector in ascending order, but, am I missing something to sort in descending order? I don't want "gsl_sort_largest" to create and extra vector.

gsl floating point data and operations

The gsl manual only mentioned that the floating point data can be represented by "gsl_vector_float" or "gsl_matrix_float", but it doesn't provide the methods to operate on these float gsl data. It even doesn't say how to allocate memory for it, and…

Implementation of GNU Scientific Library?

Does anyone know a collection of articles or books that describes the implementation of the GNU Scientific Library? This question is not about using the GSL; it's about how the GSL is implemented, their design decisions / tradeoffs. Thanks!

Can't seem to figure out what's going on here

This code exemplifies the problem in a much simpler way (sorry for the previous one, it's too complicated). Anyway, note that out_b will print out correctly for any values of index between 0 to 958. The variable out_a, however, will always print out…

I have an ODE of type: x'(t) = a(t)x+g(t) Which I am trying to solve. The only GSL ODE example isn't very helpful because the only coefficient (\mu) is not time dependent. This question has been answered on the GSL mailing list however the answer…
