Hello Stéphane,
The source code (Fortran) is available here:
http://gitweb.scilab.org/?p=scilab.git;a=blob;f=scilab/modules/sparse/sci_gateway/fortran/sci_f_sparse.f;h=6172a4fe8c7dafd2ae7e44135db9c4c4be1c9794;hb=master
Regards.

Hello Scilab devs/masters,
For performance purposes, i need to implement a function which is
missing to Scilab, allowing to set at once all non-zero terms of a
sparse matrix. Some other languages have this feature, e.g. Julia
allows to write such things.
A.nzval=v
of course this is interesting when the sparsity pattern does not
change but actual element values do. I noticed that the use of
"sparse" to reconstruct matrices in this context is the main
bottleneck of my code... In Scilab the logical name of such a command
should be "spset" and used like this
spset(A,v)
of course, the user has to be aware that Scilab sparse storage is line
compressed and thus v should be correctly ordered, but this kind of
feature is really missing. I think I can (try to) write such a
function, so my question is : where is the source code of the C
function which is interfaced as "sparse" macro in Scilab ?
S.
