?larcm

Multiplies a square real matrix by a complex matrix.

Syntax

call clarcm( m, n, a, lda, b, ldb, c, ldc, rwork )

call zlarcm( m, n, a, lda, b, ldb, c, ldc, rwork )

The routine performs a simple matrix-matrix multiplication of the form

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.

m

INTEGER. The number of rows and columns of the matrix A and of the number of rows of the matrix C (m ≥ 0).

n

INTEGER. The number of columns of the matrix B and the number of columns of the matrix C

(n ≥ 0).

a

REAL for clarcm

DOUBLE PRECISION for zlarcm

Array, DIMENSION (lda, m). Contains the m-by-m matrix A.

lda

INTEGER. The leading dimension of the array a, lda ≥ max(1, m).

b

COMPLEX for clarcm

DOUBLE COMPLEX for zlarcm

Array, DIMENSION (ldb, n). Contains the m-by-n matrix B.

ldb

INTEGER. The leading dimension of the array b, ldb ≥ max(1, n).

ldc

INTEGER. The leading dimension of the output array c, ldc ≥ max(1, m).

rwork

REAL for clarcm

DOUBLE PRECISION for zlarcm
