Add missing sparse routines (sobj, sgrad) #73

Closed jfowkes closed 6 months ago

jfowkes commented 9 months ago

The official CUTEst MATLAB interface has the sparse routines:

Tool    CUTEst function   Purpose
--------------------------------------------------------------------------
sobj    uofg / cofsg      Evaluate objective function value
                          and its sparse gradient if requested
sgrad   ugr / cisgr       Evaluate objective function or
                          constraint gradient as a sparse vector

These are the sparse equivalents of our existing obj and grad routines.

We should probably implement these in a similar way as done there: https://github.com/ralna/CUTEst/blob/master/src/matlab/mcutest.c
