## Synopsis

### Functions/Subroutines

subroutine **cget36** (rmax, lmax, ninfo, knt, nin)**CGET36**

## Function/Subroutine Documentation

### subroutine cget36 (real rmax, integer lmax, integer ninfo, integer knt, integer nin)

**CGET36**

**Purpose:**

CGET36 tests CTREXC, a routine for reordering diagonal entries of a matrix in complex Schur form. Thus, CLAEXC computes a unitary 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. 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 Number of examples where INFO is nonzero.

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

*NIN*NIN is INTEGER Input logical unit number.
