MATLAB中imshow()和image(): IMSHOW Display image in Handle Graphics figure. IMSHOW(I) displays the grayscale image I. IMSHOW(I,[LOW HIGH]) displays the grayscale image I, specifying the display range for I in [LOW HIGH]. The value LOW (and any value les
MATLAB中求矩阵非零元的坐标: 方法1: index=find(a); [i,j]=ind2sub(size(a),index); disp([i,j]) 方法2: [i,j]=find(a>0|a<0) %列出所有非零元的坐标 [i,j]=find(a==k) %找出等于k值的矩阵元素的坐标 所用函数简介: IND2SUB Multiple subscripts from linear index. IND2SUB is used to determine the equivalent
