Question

重塑我整形單元陣列時有一個問題

：

w = size(im,1);        % width size 
h = size(im,2); 
d = size(crossfield,3); 
for pxRow = 1:h % fixed pixel row 
    for pxCol = 1:w % fixed pixel column 
    for pxBreadth = 1:d  
     for r = 1:h % row of distant pixel 
     for c = 1:w % column of distant pixel 
      for z = 1:d 

      field(c,r,z) = crossfield(c,r,z).*rmatrix(c,r,z);     

      end 
     end 
     end 
    b(i) = {field}; % filling a cell array with results. read below 
    i = i+1; 
    end 
    end 
end 

b = reshape(b, w, h,z); 

和錯誤：

Error using ==> reshape

To RESHAPE the number of elements must not change.

某些其他信息，其可以是使用的：

>> size(im) 

ans = 

    35 35 

>> size(crossfield) 

ans = 

    35 35  3 

>> size(rmatrix) 

ans = 

    35 35  3 
>> size(w) 

ans = 

    1  1 

我該如何重塑b？

Answer 1

請注意，你的三個內環具有相同的效果做

field = crossfield .* rmatrix; 

和你的三個外環剛單元陣列b的每一個元素設置爲相同的值。因此你的代碼可以簡化爲：

[w h] = size(im); 
d = size(crossfield,3); 

b = cell(w,h,d); 
b(:,:,:) = {crossfield .* rmatrix};
