Numlib does this, though dimensions (1 or 2) must be passed as separate arguments, and instead of a pointer often a var variable of the cell type is used. determinants, eigen values, quite some is there. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
