Detailed Description
Function Documentation
subroutineclacp2(characteruplo,integerm,integern,real,dimension(lda,*)a,integerlda,complex,dimension(ldb,*)b,integerldb)CLACP2 copies all or part of a real two-dimensional array to a complex array.
Purpose:
CLACP2 copies all or part of a real two-dimensional matrix A to a
complex matrix B.
ParametersUPLO
UPLO is CHARACTER*1
Specifies the part of the matrix A to be copied to B.
= 'U': Upper triangular part
= 'L': Lower triangular part
Otherwise: All of the matrix A
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
A
A is REAL array, dimension (LDA,N)
The m by n matrix A. If UPLO = 'U', only the upper trapezium
is accessed; if UPLO = 'L', only the lower trapezium is
accessed.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B
B is COMPLEX array, dimension (LDB,N)
On exit, B = A in the locations specified by UPLO.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,M).
