lapack_int LAPACKE_zlarcm(int matrix_layout,lapack_int m,lapack_int n,const double * a,lapack_int lda,const lapack_complex_double *b,lapack_int ldb,lapack_complex_double *c ,lapack_int ldc);

Description

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, and C is m-by-n and complex.

Input Parameters

m

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

n

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

(n≥ 0).

a

Array, size [lda* m]. Contains the m-by-m matrix A.

lda

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

b

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

ldb

The leading dimension of the array b, ldb≥max(1, m) for column-major layout; ldb≥max(1, n) for row-major layout .

ldc

The leading dimension of the array c, ldc≥max(1, m) for column-major layout; ldc≥max(1, n) for row-major layout .

Output Parameters

c

Array, size (ldc, n). Contains the m-by-n matrix C.

Return Values

This function returns a value info. If info = 0, the execution is successful. If info = -i, parameter i had an illegal value.
