[MATLAB图像处理] matlab图像在3D显示屏上混叠采样处理

[雨鼓阳光]

我的程序是先编译一张测试条纹图，然后对这个条纹图放到模拟3D坐标的显示器中，因为显示器的采样点不发生变化，因而当感觉图像显示凸出显示器时会产生混叠公式z=e*V/(e-d); x=V./z.*c-d./2; y=V./z.*r; 因为是显示器上的，那么x和y的值必须取整数。下面是我的程序，哪位大神能帮我修改下。 e=65mm是瞳距，V=600mm是观看距离，d=-24mm是视差，显示器的分辨率是0.4mm。

M=300;
N=300;
u0=50;
v0=50;
A=10;

c=0:M-1;
r=0:N-1;
[C,R]=meshgrid(c,r);
g=A*sin(u0*R+v0*C);
g=mat2gray(g)
imshow(g)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%   mix  %%%

e=65*2.5;
d=-24*2.5;
V=600*2.5;
z=e*V/(e-d);
for c=1:M-1
    for r=1:N-1
       x=round((e.*(2.*c+d))/(2.*(e-d)));               
        y=round((e.*r)/(e-d));                             
        h=zeros(x,y);
        h(x,y)=g(c,r);
    end
end
imshow(h,[]);
%h=mat2gray(h)
figure

错误??? Attempted to access g(0,0); index must be a positive integer or logical.
Error in ==> Untitled4 at 25
h(x,y)=g(c,r);

这是什么错误，怎么修改啊
