Hi,
I need to work with (scalar or not) functions of vector,
matrix variables (or more generally variables with
multiples indices). Typically I would start with a
function where all indices are summed over, but I would
need to take derivatives with respect to a given matrix elements,
and then sum the resulting derivatives over all possible indices,
minimize this function of many variables with respect
to all entries etc. Is there an easy way to do it, that
is keeping indices and summations in the expressions?


Thanks,
Yuri Shirman
