**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 T Put T to test the driver routines T Put T to test the error exits SGE 11 List types on next line if 0 < NTYPES < 11 SGB 8 List types on next line if 0 < NTYPES < 8 SGT 12 List types on next line if 0 < NTYPES < 12 SPO 9 List types on next line if 0 < NTYPES < 9 SPS 9 List types on next line if 0 < NTYPES < 9 SPP 9 List types on next line if 0 < NTYPES < 9 SPB 8 List types on next line if 0 < NTYPES < 8 SPT 12 List types on next line if 0 < NTYPES < 12 SSY 10 List types on next line if 0 < NTYPES < 10 SSR 10 List types on next line if 0 < NTYPES < 10 SSK 10 List types on next line if 0 < NTYPES < 10 SSA 10 List types on next line if 0 < NTYPES < 10 SS2 10 List types on next line if 0 < NTYPES < 10 SSP 10 List types on next line if 0 < NTYPES < 10 STR 18 List types on next line if 0 < NTYPES < 18 STP 18 List types on next line if 0 < NTYPES < 18 STB 17 List types on next line if 0 < NTYPES < 17 SQR 8 List types on next line if 0 < NTYPES < 8 SRQ 8 List types on next line if 0 < NTYPES < 8 SLQ 8 List types on next line if 0 < NTYPES < 8 SQL 8 List types on next line if 0 < NTYPES < 8 SQP 6 List types on next line if 0 < NTYPES < 6 DQK 19 List types on next line if 0 < NTYPES < 19 STZ 3 List types on next line if 0 < NTYPES < 3 SLS 6 List types on next line if 0 < NTYPES < 6 SEQ SQT SQX STS SHH
