I don't know if this is necessary, but the scaling of a complex (sparse)
matrix with a real vector, complex sparse matrix-vector multiplication, and
unpacking(in place) a complex vector could be added. I had to somehow do the
above-mentioned stuff while solving a time-harmonic FE problem.
There are alloc and calloc for the blocks and vectors. Is there any particular
reason for not having anything to resize a block or a vector?
In gsl/spmatrix/getset_source.c, _set() replaces the matrix elements, could it
be possible to assemble the matrix as
*(BASE*) ptr = *(BASE*) + x;
and copy the entire code to a new name.
