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
