## Synopsis

### Functions/Subroutines

subroutine **sget36** (rmax, lmax, ninfo, knt, nin)**SGET36**

## Function/Subroutine Documentation

### subroutine sget36 (real rmax, integer lmax, integer, dimension( 3 ) ninfo, integer knt, integer nin)

**SGET36**

**Purpose:**

SGET36 tests STREXC, a routine for moving blocks (either 1 by 1 or 2 by 2) on the diagonal of a matrix in real Schur form. Thus, SLAEXC computes an orthogonal matrix Q such that Q' * T1 * Q = T2 and where one of the diagonal blocks of T1 (the one at row IFST) has been moved to position ILST. The test code verifies that the residual Q'*T1*Q-T2 is small, that T2 is in Schur form, and that the final position of the IFST block is ILST (within +-1). The test matrices are read from a file with logical unit number NIN.

**Parameters***RMAX*RMAX is REAL Value of the largest test ratio.

*LMAX*LMAX is INTEGER Example number where largest test ratio achieved.

*NINFO*NINFO is INTEGER array, dimension (3) NINFO(J) is the number of examples where INFO=J.

*KNT*KNT is INTEGER Total number of examples tested.

*NIN*NIN is INTEGER Input logical unit number.
