CRRCR
Copies a real rectangular matrix to a complex rectangular matrix.
Required Arguments
A — Real NRA by NCA rectangular matrix. (Input)
B — Complex NRB by NCB rectangular matrix containing a copy of A. (Output)
Optional Arguments
NRA — Number of rows in A. (Input)
Default: NRA = SIZE (A,1).
NCA — Number of columns in A. (Input)
Default: NCA = SIZE (A,2).
LDA — Leading dimension of A exactly as specified in the dimension statement of the calling program. (Input)
Default: LDA = SIZE (A,1).
NRB — Number of rows in B. (Input)
It must be the same as NRA.
Default: NRB = SIZE (B,1).
NCB — Number of columns in B. (Input)
It must be the same as NCA.
Default: NCB = SIZE (B,2).
LDB — Leading dimension of B exactly as specified in the dimension statement of the calling program. (Input)
Default: LDB = SIZE (B,1).
FORTRAN 90 Interface
Generic: CALL CRRCR (A, B [, …])
Specific: The specific interface names are S_CRRCR and D_CRRCR.
FORTRAN 77 Interface
Single: CALL CRRCR (NRA, NCA, A, LDA, NRB, NCB, B, LDB)
Double: The double precision name is DCRRCR.
Description
The routine CRRCR copies a real rectangular matrix to a complex rectangular matrix.
Example
A 3 × 2 real matrix is copied to a 3 × 2 complex matrix.
