## Functions

subroutine | ctpqrt2 (m, n, l, a, lda, b, ldb, t, ldt, info)
| CTPQRT2 computes a QR factorization of a real or complex "triangular-pentagonal" matrix, which is composed of a triangular block and a pentagonal block, using the compact WY representation for Q.
subroutine | dtpqrt2 (m, n, l, a, lda, b, ldb, t, ldt, info)
| DTPQRT2 computes a QR factorization of a real or complex "triangular-pentagonal" matrix, which is composed of a triangular block and a pentagonal block, using the compact WY representation for Q.
subroutine | stpqrt2 (m, n, l, a, lda, b, ldb, t, ldt, info)
| STPQRT2 computes a QR factorization of a real or complex "triangular-pentagonal" matrix, which is composed of a triangular block and a pentagonal block, using the compact WY representation for Q.
subroutine | ztpqrt2 (m, n, l, a, lda, b, ldb, t, ldt, info)
| ZTPQRT2 computes a QR factorization of a real or complex "triangular-pentagonal" matrix, which is composed of a triangular block and a pentagonal block, using the compact WY representation for Q.
