QR

QR Decomposition done in place. More...

Device pointer interface: qr decomposition
Parameters: [out] d_tau Vector on device. Size: min(m, n). contains Additional information about d_Q [out] d_R The upper triangular matrix. Size: (k, n) [in,out] d_Q If d_R isn't NULL, d_Q contains orthogonal matrix. Size: (m, k) if d_R is NULL, d_Q contains the packed version of qr decomposition. Size: (m, n) [in] m number of rows in the input [in] n number of columns in the input [in] k number of columns to be calculated in the orthogonal matrix. [in] batch Number of tiles of input being handled.
