Purpose:

 ZLARCM performs a very simple matrix-matrix multiplication:
          C := A * B,
 where A is M by M and real; B is M by N and complex;
 C is M by N and complex.

Parameters

[in]	M	M is INTEGER The number of rows of the matrix A and of the matrix C. M >= 0.
[in]	N	N is INTEGER The number of columns and rows of the matrix B and the number of columns of the matrix C. N >= 0.
[in]	A	A is DOUBLE PRECISION array, dimension (LDA, M) On entry, A contains the M by M matrix A.
[in]	LDA	LDA is INTEGER The leading dimension of the array A. LDA >=max(1,M).
[in]	B	B is COMPLEX*16 array, dimension (LDB, N) On entry, B contains the M by N matrix B.
[in]	LDB	LDB is INTEGER The leading dimension of the array B. LDB >=max(1,M).
[out]	C	C is COMPLEX*16 array, dimension (LDC, N) On exit, C contains the M by N matrix C.
[in]	LDC	LDC is INTEGER The leading dimension of the array C. LDC >=max(1,M).
[out]	RWORK	RWORK is DOUBLE PRECISION array, dimension (2*M*N)
