sumsquareddifference.m

有监督自组织映射-偏最小二乘算法(A supervised self-organising map–partial least squares algorithm),可以用语多变量数据的回归分析

function [SSDiff] = SumSquaredDifference(OldMap,NewMap);

[Nrow, Ncol] = size(OldMap);

SSDiff=0;
for i=1:Nrow
    for j=1:Ncol
        SSDiff = SSDiff + (OldMap(i,j)-NewMap(i,j))^2;
    end
end
