matlab循环向量化

Question

我想知道是否有人可以帮助我将这些 for 循环矢量化，我尝试了几次但未能提前感谢。

pixel_depth = 16; 
pixel_range = 2^pixel_depth -1;

for i=1:height

    for j=1:width

        for k=1:gaussianComponents

           mean(i,j,k) = rand*pixel_range; 

           weights(i,j,k) = 1/gaussianComponents; 

           pixelDeviation(i,j,k) = diviationNew; 

       end

    end

 end

感谢您的帮助....

Answer 1

mean = rand(height, width, gaussianComponents) * pixel_range;

weights = 1/gaussianComponents * ones(height, width, gaussianComponents);

pixelDeviation = diviationNew * ones(height, width, gaussianComponents);

请注意，mean 是变量的错误名称，因为它会隐藏 mean 函数。
