CLACP2 copies all or part of a real two-dimensional array to a complex array.

Function/Subroutine Documentation

subroutine clacp2 (character uplo, integer m, integer n, real, dimension( lda, * ) a, integer lda, complex, dimension( ldb, * ) b, integer ldb)

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.

Parameters

UPLO



          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 is INTEGER


          The number of rows of the matrix A.  M >= 0.



          N is INTEGER


          The number of columns of the matrix A.  N >= 0.



          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 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).
