Matlab绘制网格图


%%%   结点坐标矩阵 
LX = 18; LY = 3; 
nx = 24; ny = 6; 
np = (nx+1)*(ny+1); 
XY = zeros(np,2); 
for i = 1:np-(ny+1); j = 1:ny; 
    XY(i+(ny+1),1) = XY(i,1) + LX/nx; 
    XY(j+1,2) = XY(j,2) + LY/ny; 
    XY(i+ny+1,2) = XY(i,2) + 0; 
end 
for i = 1:np-7; j = 1:np-7; 
    line([XY(i,1),XY(i+1,1),XY(i+7,1)],... 
         [XY(1,2),XY(i+1,2),XY(i+7,2)]); 
end

这该怎么该才能画出图片中的那样啊？

啊，你直接用画图功能不就画出来了
