## Functions/Subroutines

subroutine zlat2c (UPLO, N, A, LDA, SA, LDSA, INFO)

ZLAT2C converts a double complex triangular matrix to a complex triangular matrix.

# Function/Subroutine Documentation

## subroutine zlat2c (characterUPLO, integerN, complex*16, dimension( lda, * )A, integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO)

ZLAT2C converts a double complex triangular matrix to a complex triangular matrix.
Purpose:
``` ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX
triangular matrix, A.

RMAX is the overflow for the SINGLE PRECISION arithmetic
ZLAT2C checks that all the entries of A are between -RMAX and
RMAX. If not the convertion is aborted and a flag is raised.

This is an auxiliary routine so there is no argument checking.
```
Parameters:
UPLO
```          UPLO is CHARACTER*1
= 'U':  A is upper triangular;
= 'L':  A is lower triangular.
```
N
```          N is INTEGER
The number of rows and columns of the matrix A.  N >= 0.
```
A
```          A is COMPLEX*16 array, dimension (LDA,N)
On entry, the N-by-N triangular coefficient matrix A.
```
LDA
```          LDA is INTEGER
The leading dimension of the array A.  LDA >= max(1,N).
```
SA
```          SA is COMPLEX array, dimension (LDSA,N)
Only the UPLO part of SA is referenced.  On exit, if INFO=0,
the N-by-N coefficient matrix SA; if INFO>0, the content of
the UPLO part of SA is unspecified.
```
LDSA
```          LDSA is INTEGER
The leading dimension of the array SA.  LDSA >= max(1,M).
```
INFO
```          INFO is INTEGER
= 0:  successful exit.
= 1:  an entry of the matrix A is greater than the SINGLE
PRECISION overflow threshold, in this case, the content
of the UPLO part of SA in exit is unspecified.
