Proximity Matrix Decomposition
Description
Additive decomposition of an asymmetric, square proximity matrix into a symmetric matrix and an skew-symmetric matrix
Usage
symdecomp(P)
Arguments
P |
Square proximity matrix |
Details
Performs the decompositon P = M + N
(M and N are orthogonal).
Value
Returns the following matrices:
M |
symmetric component |
N |
skew-symmetric component |
