# complex\_lin(3)

complex

## NAME

complex\_lin - complex

## SYNOPSIS

### Functions

program **cchkaa**\
 **CCHKAA**

## Detailed Description

This is the group of complex LAPACK TESTING LIN routines.

## Function Documentation

### program cchkaa

**CCHKAA**

**Purpose:**

```
 CCHKAA is the main test program for the COMPLEX linear equation
 routines.
 The program must be driven by a short data file. The first 15 records
 (not including the first comment  line) specify problem dimensions
 and program options using list-directed input. The remaining lines
 specify the LAPACK test paths and the number of matrix types to use
 in testing.  An annotated example of a data file can be obtained by
 deleting the first 3 characters from the following 42 lines:
 Data file for testing COMPLEX LAPACK linear equation routines
 7                      Number of values of M
 0 1 2 3 5 10 16        Values of M (row dimension)

 0 1 2 3 5 10 16        Values of N (column dimension)
 1                      Number of values of NRHS
 2                      Values of NRHS (number of right hand sides)
 5                      Number of values of NB
 1 3 3 3 20             Values of NB (the blocksize)
 1 0 5 9 1              Values of NX (crossover point)
 3                      Number of values of RANK
