int fmpz_mod_mat_reduce_row(slong * column, fmpz_mod_mat_t A, slong * P, slong * L, slong m, const fmpz_mod_ctx_t ctx)source

Reduces row m of A against the earlier rows, with the conventions of gr_mat_reduce_row: P[i] is the row with its pivot in column i, or -1; L[i] bounds the nonzero columns of row i. Sets *column to the pivot column of the reduced row (made monic and recorded in P), or to -1 if the row becomes zero. Returns GR_SUCCESS, or GR_DOMAIN if the new pivot is not invertible. The sums are accumulated exactly and each entry is reduced once, when it is reached.
