????????photo_matrix=imresize（photo_matrix[16?16]）;
????????photo_matrix=uint8（photo_matrix<=230）;
????????%thresh=graythresh（photo_matrix）;%確定二值化閾值
????????%photo_matrix=im2bw（photo_matrixthresh）;%對圖像二值化
????????tmp=photo_matrix‘;
????????tmp=tmp（:）;
????????%計算輸入層輸入
????????x=double（tmp‘）;
????????%得到隱層輸入
????????y0=x*V;
????????%激活
????????y=1./（1+exp（-y0*yita1））;
????????%得到輸出層輸入
????????o0=y*W;
????????o=1./（1+exp（-o0*yita1））;
????????%最大的輸出即是識別到的數字
