Need of "in place" format conversions
For the sake of memory economy, we used to convert IJV (a.k.a. COO) matrices to the CSC format by a call to the Sparskit
SUBROUTINE coocsr_inplace ( n, nnz, job, a, ja, ia, iwk )
We wonder if spmConvert works in place or generate a second full spm and replaces the INOUT argument before returning.
Notice that coocsr_inplace only needs an integer work array
