Copies a complex band matrix stored in complex band storage mode.

Required Arguments

A — Complex band matrix of order N.   (Input)

NLCA — Number of lower codiagonals in A.   (Input)

NUCA — Number of upper codiagonals in A.   (Input)

B — Complex matrix of order N containing a copy of A.   (Output)

NLCB — Number of lower codiagonals in B.   (Input)
NLCB must be at least as large as NLCA.

NUCB — Number of upper codiagonals in B.   (Input)
NUCB must be at least as large as NUCA.

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 CCBCB (A, NLCA, NUCA, B, NLCB, NUCB [,…])

Specific:          The specific interface names are S_CCBCB and D_CCBCB.

FORTRAN 77 Interface

Single:             CALL CCBCB (N, A, LDA, NLCA, NUCA, B, LDB, NLCB, NUCB)

Double:           The double precision name is DCCBCB.

Description

The routine CCBCB copies the complex band matrix A in band storage mode into the complex band matrix B in band storage mode.

Example

A complex band matrix of order 3 in band storage mode with one upper codiagonal and one lower codiagonal is copied into another complex band matrix in band storage mode.
