Library: xclust
See also: mat2vec distance lpdist agglom corrdist

Macro: vec2mat
Description: stores the values of a vector into the upper triangle of a symmetric matrix regarding the sequence described in agglom

Usage: d = vec2mat(v)
Input:
v n(n-1)/2 x 1 matrix containing the values of the upper triangle of a symmetric matrix
Output:
d n x n symmetric matrix with zeros in the diagonal

Example:
; load the library xclust
library ("xclust")
; generate vector
v = #(2, 3, 7, 1, 8, 5)
; apply vec2mat
vec2mat(v)
Result:
