| Description: | Decomposes an orthonormal matrix into a set of rotation matrices. |
| Usage: | {out, d} = mat2rot(in) | |
| Input: | ||
| in | p x p matrix | |
| Output: | ||
| out | p x (p-1)/2 vector | |
| d | p x 1 vector | |

; generate some orthonormal matrix
x = normal(6,6)
; orthonormalize x
o = orthonormal(x)
; check it
o'*o
; compute givensrot
{out, d} = mat2rot(o)
out
gives the appropriate (6x6) identity matrix and shows the angle of the appropriate rotations
