%?函數KernelMatrix
%?最后生成的核矩陣在KM里面保存

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
function?[KM]?=?KernelMatrix（TrainMatrixSigma）

%?求解訓練矩陣的大小
[RowsColumns]?=?size（TrainMatrix）;?
%fprintf（1‘Total?%d?points?in?%d?dimensions\n‘RowsColumns）;

%?生成一個大小為樣本點個數相同的0方陣列
%KM?=?zeros（RowsRows）

%?N為核矩陣上三角的個數，因為核矩陣是對稱的，所以只要給上三角賦值就可了
%N?=?（Rows*Rows-Rows）/2+Rows;
for?i=1:Rows
????for?j=1:Rows
????????s?=?TrainMatrix（i:）?-?TrainMatrix（j:）;
????????t?=?norm（s）;
????????KM（ij）?=?exp（-（t^2）/（Sigma^2））;
????end
end
