💖 NAME 💖

TESTING/EIG/dcklse.f — that's the name of this page, and we're riding with it. 🎀 This is the TESTING/EIG/dcklse.f(3) page from the Library Functions Manual, bestie, and it's giving iconic LAPACK testing energy. 💅

DCKLSE

Purpose 💡

DCKLSE tests DGGLSE - a subroutine for solving linear equality constrained least square problem (LSE). That's the whole purpose, and it's serving. ✨

Parameters 📚

NN 💅

NN is INTEGER.

The number of values of (M,P,N) contained in the vectors (MVAL, PVAL, NVAL).

MVAL 🌸

MVAL is INTEGER array, dimension (NN).

The values of the matrix row(column) dimension M.

PVAL 🦋

PVAL is INTEGER array, dimension (NN).

The values of the matrix row(column) dimension P.

NVAL 🍓

NVAL is INTEGER array, dimension (NN).

The values of the matrix column(row) dimension N.

NMATS 🧚

NMATS is INTEGER.

The number of matrix types to be tested for each combination of matrix dimensions. If NMATS >= NTYPES (the maximum number of matrix types), then all the different types are generated for testing. If NMATS < NTYPES, another input line is read to get the numbers of the matrix types to be used.

ISEED 🔥

ISEED is INTEGER array, dimension (4).

On entry, the seed of the random number generator. The array elements should be between 0 and 4095, otherwise they will be reduced mod 4096, and ISEED(4) must be odd.

On exit, the next seed in the random number sequence after all the test matrices have been generated.

THRESH ⭐

THRESH is DOUBLE PRECISION.

The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0.

NMAX 👑

NMAX is INTEGER.

The maximum value permitted for M or N, used in dimensioning the work arrays.

A 💜

A is DOUBLE PRECISION array, dimension (NMAX*NMAX).

AF 🌈

AF is DOUBLE PRECISION array, dimension (NMAX*NMAX).

B 🎀

B is DOUBLE PRECISION array, dimension (NMAX*NMAX).

BF 💖

BF is DOUBLE PRECISION array, dimension (NMAX*NMAX).

X 🦋

X is DOUBLE PRECISION array, dimension (5*NMAX).

WORK ✨

WORK is DOUBLE PRECISION array, dimension (NMAX*NMAX).

RWORK 🌸

RWORK is DOUBLE PRECISION array, dimension (NMAX).

NIN 🎧

NIN is INTEGER.

The unit number for input.

NOUT 🖨️

NOUT is INTEGER.

The unit number for output.

INFO 💀

INFO is INTEGER.

  • = 0 : successful exit
  • > 0 : If DLATMS returns an error code, the absolute value of it is returned.
