/* (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = */
/* .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. */
/* NN (input) INTEGER */
/* The number of values of N contained in the vector NVAL. */
/* NVAL (input) INTEGER array, dimension (NN) */

/* The number of values of NB contained in the vector NBVAL. */
/* NBVAL (input) INTEGER array, dimension (NBVAL) */
/* The values of the block size NB. */
/* NRANK (input) INTEGER */
/* The number of values of RANK contained in the vector RANKVAL. */
/* RANKVAL (input) INTEGER array, dimension (NBVAL) */
/* The values of the block size NB. */
/* THRESH (input) DOUBLE PRECISION */
/* The threshold value for the test ratios. A result is */

/* every test ratio printed, use THRESH = 0. */
/* TSTERR (input) LOGICAL */
/* Flag that indicates whether error exits are to be tested. */
/* NMAX (input) INTEGER */
/* The maximum value permitted for N, used in dimensioning the */
/* work arrays. */
