| Jun 27, 2011 at 8:43 | comment | added | FxIII | To be picky: symmetry is necessary and sufficient for real matrices that has to be decomposed to real factors. If the second falls then the necessarity falls (which is good); if the first falls then the sufficiency falls (which is bad). But who cares?:) | |

| Jun 26, 2011 at 17:12 | comment | added | Samaursa | WildMagic5 (geometrictools.com) engine does it with its Matrix library. So does Ogre's (ogre3d.org/docs/api/html/classOgre_1_1Matrix3.html). You are right that not all matrices can be solved for. In this case, they must be symmetric. | |
| Jun 26, 2011 at 17:02 | comment | added | FxIII | can you name a library that does this for 2x2 or 3x3 matrices? Not all the matrices can be spectral decomposed, I see little 3x3 applications that can and they don't do something interisting. | |
