Examples With Orthogonal/Unitary Factors

All examples are in 03_Orthogonal_Factors/. Block and thread execution variants are provided.

• geqrf_batched_block.cu, geqrf_batched_thread.cu

These examples compute QR factorization on batched M x N matrices. Results are compared with the cuBLAS host API cublas<t>geqrfBatched.

• ungqr_batched_block.cu, ungqr_batched_thread.cu

These examples form the orthogonal/unitary matrix Q from the QR factorization of a batched M x N matrix. Results are compared with the cuSolver host API cusolverDnXungqr.

• unmqr_batched_block.cu, unmqr_batched_thread.cu

These examples multiply a batched matrix by the orthogonal/unitary matrix Q from QR factorization. Results are compared with the cuSolver host API cusolverDnXunmqr.
