I suppose you could use dgemm with alpha = 0. and dummy arguments for A and B. I don't know if there would be any advantage in doing the calculation this way. The C declaration corresponding to the Fortran subroutine is /* Level 3 BLAS */ /* DGEMM - perform one of the matrix-matrix operations */ /* C := alpha*op( A )*op( B ) + beta*C, */ void F77_NAME(dgemm)(const char *transa, const char *transb, const int *m, const int *n, const int *k, const double *alpha, const double *a, const int *lda, const double *b, const int *ldb, const double *beta, double *c, const int *ldc); ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
