◆ DETERMINANT_START

#define DETERMINANT_START

Value:

    SEXP dim = GET_SLOT(obj, Matrix_DimSym); \
    int *pdim = INTEGER(dim), m = pdim[0], n = pdim[1]; \
    if (m != n) \
        error(_("determinant of non-square matrix is undefined")); \
    int givelog = asLogical(logarithm) != 0; \
    double modulus = 0.0; /* result for n == 0 */
