在 MATLAB Online 中打开

clc; clear all ;
x = linspace(0,1,11) ;
y = linspace(0,1,11) ;
[X,Y] = meshgrid(x,y) ;
Z = zeros(size(X)) ;
Z(4:7,:) = 1 ;
surf(X,Y,Z,'edgecolor','b') ;
view([0 90])
colormap('gray')
axis off

You make Z values '1' according to your attached pictures, you can generate others.

I am sorry I didn't make the question clearly. In fact, my question is suppose I have a 9x9 matrix (black means 0 and white means 1, just like the first one in the picture), how can I generate others matrixs ( like the others from two to nine in the picture) by rotating the first one?
