18 ZLARCM performs a very simple matrix-matrix multiplication:
19 C := A * B,
20 where A is M by M and real; B is M by N and complex;
21 C is M by N and complex.
22
23
25 M (input) INTEGER
26 The number of rows of the matrix A and of the matrix C. M >=
27 0.
28
29 N (input) INTEGER
30 The number of columns and rows of the matrix B and the number
31 of columns of the matrix C. N >= 0.
32
33 A (input) DOUBLE PRECISION array, dimension (LDA, M)
34 A contains the M by M matrix A.
35
36 LDA (input) INTEGER
37 The leading dimension of the array A. LDA >=max(1,M).
38
39 B (input) DOUBLE PRECISION array, dimension (LDB, N)
40 B contains the M by N matrix B.
41
42 LDB (input) INTEGER
43 The leading dimension of the array B. LDB >=max(1,M).
44
45 C (input) COMPLEX*16 array, dimension (LDC, N)
46 C contains the M by N matrix C.
47
48 LDC (input) INTEGER
49 The leading dimension of the array C. LDC >=max(1,M).
