NAME

clag2z.f -

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
