| Sep 12, 2017 at 20:38 | comment | added | Tolga Birdal | This is similar to @Will P.'s comment. I do not suppose that it is good enough. That's the reason why I ask further opinions. MGS didn't fail yet though. | |
| Sep 12, 2017 at 20:31 | comment | added | rchilton1980 | Is MGS really not good enough? The problem statement almost insists upon this algorithm (seeking explicit tabulation of Q and want to include some specific v in Q). Have you tried taking a random DxD matrix, overwriting the first column with v, and MGS'ing it? How did it fail? Alternatively, you could make a random Dx(D-1) matrix, project v off from each column, then use some other QR algorithm (householder, perhaps column pivoting, etc). You would reconstruct V/Q explicitly in a second pass (dorgqr-like routine, or apply Q to identity using dormqr-like routine) | |
