MAKESYM

Make a dissimilarity matrix symmetric

    [B,C] = MAKESYM(A,PROC)
    [B,C] = A*MAKESYM(PROC)

Input
A	Square dataset or matrix
PROC	String with procedure: 'average' (default), 'min', 'max',  'lower' (use lower triangle part) or 'upper' (user upper part).

Output
B	Symmetric dataset or matrix computed as (A+A')/2
C	Asymmetric remaining part, dataset or matrix computed as (A-A')/2

Description

B is a symmetric matrix obtained combining A and A' by PROC.
