matlab for循环矢量化

Question

我想知道是否有人可以帮助我矢量化这些循环我有几次尝试，但一直未能提前感谢。

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); 

注意mean是一个可变的名声，因为它会隐藏mean功能。
