std::size_t ADS::compressTriplets(std::size_t nmajor, std::size_t nminor, std::size_t z, const J *major, const J *minor, const V *value, I *beg, I *ind, V *val, AssemblyWorkspace<I, V> &work)

the compressed form, by major index, of the z triplets ( major[ k ] , minor[ k ] , value[ k ] ) of a matrix of nmajor x nminor, the values of equal places summed: beg[ 0 .

. nmajor ], and the minor indices and the values in ind and val, increasing in each major index; the number of the entries

Pre:

the indices are below nmajor and nminor, beg has nmajor + 1 places, ind and val at least z, and z fits I
