M >= 0. .TP 8 N (input) INTEGER The number of columns and rows of the matrix B and the number of columns of the matrix C. N >= 0. .TP 8 A (input) DOUBLE PRECISION array, dimension (LDA, M) A contains the M by M matrix A. .TP 8 LDA (input) INTEGER The leading dimension of the array A. LDA >=max(1,M). .TP 8 B (input) DOUBLE PRECISION array, dimension (LDB, N) B contains the M by N matrix B. .TP 8 LDB (input) INTEGER The leading dimension of the array B. LDB >=max(1,M). .TP 8 C (input) COMPLEX*16 array, dimension (LDC, N) C contains the M by N matrix C. .TP 8 LDC (input) INTEGER The leading dimension of the array C. LDC >=max(1,M). .TP 8 RWORK (workspace) DOUBLE PRECISION array, dimension (2*M*N)
