CCGCG
Copies a complex general matrix.
Required Arguments
A — Complex matrix of order N. (Input)
B — Complex matrix of order N containing a copy of A. (Output)
Optional Arguments
N — Order of the matrices A and B. (Input)
Default: N = 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).
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 CCGCG (A, B [])
Specific: The specific interface names are S_CCGCG and D_CCGCG.
FORTRAN 77 Interface
Single: CALL CCGCG (N, A, LDA, B, LDB)
Double: The double precision name is DCCGCG.
Description
The routine CCGCG copies the complex N × N general matrix A into the complex N × N general matrix B.
Example
A complex 3 × 3 general matrix is copied into another complex 3 × 3 general matrix.
