SYNOPSIS

  Functions/Subroutines

subroutine clag2z (M, N, SA, LDSA, A, LDA, INFO)
CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

Function/Subroutine Documentation

  subroutine clag2z (integerM, integerN, complex, dimension( ldsa, * )SA, integerLDSA, complex*16, dimension( lda, * )A, integerLDA, integerINFO)

CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

Purpose:

     CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A.

     Note that while it is possible to overflow while converting
     from double to single, it is not possible to overflow when
     converting from single to double.

     This is an auxiliary routine so there is no argument checking.

Parameters:
    M

              M is INTEGER
              The number of lines of the matrix A.  M >= 0.

    N

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

    SA

              SA is COMPLEX array, dimension (LDSA,N)
              On entry, the M-by-N coefficient matrix SA.

    LDSA

              LDSA is INTEGER
              The leading dimension of the array SA.  LDSA >= max(1,M).

    A

              A is COMPLEX*16 array, dimension (LDA,N)
              On exit, the M-by-N coefficient matrix A.

    LDA

              LDA is INTEGER
              The leading dimension of the array A.  LDA >= max(1,M).

    INFO

              INFO is INTEGER
              = 0:  successful exit
