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 (integer M, integer N, complex, dimension( ldsa, * ) SA, integer LDSA, complex*16, dimension( lda, * ) A, integer LDA, integer INFO)

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
