matlab for循環矢量化

Question

我想知道是否有人可以幫助我矢量化這些循環我有幾次嘗試，但一直未能提前感謝。

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 

感謝您的幫助....

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是一個可變的名聲，因爲它會隱藏mean功能。
