用于循环矢量化的matlab

Question

我想知道是否有人可以帮助我对这些循环进行矢量化我已尝试过一段时间但未能提前感谢。

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。
