Hello,
I have a 3 dimensional logical array . The size of the 3rd dimension changes and I want to convert it to 2dimensional layer.
Currently I do it this way:
% masks is the 3d logical array
[xMask,yMask,zMask]=size(masks);
mask_result= zeros(xMask,yMask);
for m=1: zMask
mask_result = mask_result | masks(:,:,m);
end
Is there a more elegant way to do it ?

请先登录，再回答此问题。

The any function can do this for you:
mask_result=any(masks,3)
