**SCHKAA**

# Detailed Description¶

This is the group of real LAPACK TESTING LIN routines.

# Function Documentation¶

## program schkaa¶

**SCHKAA**

**Purpose:**

SCHKAA is the main test program for the REAL LAPACK

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 40 lines:

Data file for testing REAL LAPACK linear eqn. routines

7 Number of values of M

0 1 2 3 5 10 16 Values of M (row dimension)

7 Number of values of N

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

30 50 90 Values of rank (as a % of N)

20.0 Threshold value of test ratio

T Put T to test the LAPACK routines
