Detailed Description

Function 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

                     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).
