Hi, I have 3x3x3 array and I can print elements on txt like this:

    A(:,:,1)=[1 2 4 ; 5 2 1 ; 6 2 1];
    A(:,:,2)=[4 6 1 ; 8 0 3 ; 1 2 4];
    A(:,:,3)=[5 8 2 ; 4 4 4 ; 1 0 0];
    function PrintArray(A)
    MyText=fopen('Text1.txt','wt');
    for i=1:size(A,1)
      for j=1:size(A,2)
        for k=1:size(A,3)
          PrintedVal=A(i,j,k);
          fprintf(MyText,'A(%d,%d,%d) = %d  \n',i,j,k,PrintedVal) ;
        end
      end
    end
    fclose(MyText);
    end

I am looking for a script that it will automatically detect the number of dimensions, will be able to perform in 2D or 4D.

Thanks for helping.

在 MATLAB Online 中打开

A(:,:,1) = [1,2,4;5,2,1;6,2,1];
A(:,:,2) = [4,6,1;8,0,3;1,2,4];
A(:,:,3) = [5,8,2;4,4,4;1,0,0];
D = ndims(A);
F = repmat(',%d',1,D);
F = sprintf('A(%s) = %%d\n',F(2:end));
C = cell(1,D);
for k = 1:numel(A)
    [C{:}] = ind2sub(size(A),k);
    fprintf(F,C{:},A(k))
end
A(1,1,1) = 1
A(2,1,1) = 5
A(3,1,1) = 6
A(1,2,1) = 2
A(2,2,1) = 2
A(3,2,1) = 2
A(1,3,1) = 4
A(2,3,1) = 1
A(3,3,1) = 1
A(1,1,2) = 4
A(2,1,2) = 8
A(3,1,2) = 1
A(1,2,2) = 6
A(2,2,2) = 0
A(3,2,2) = 2
A(1,3,2) = 1
A(2,3,2) = 3
A(3,3,2) = 4
A(1,1,3) = 5
A(2,1,3) = 4
A(3,1,3) = 1
A(1,2,3) = 8
A(2,2,3) = 4
A(3,2,3) = 0
A(1,3,3) = 2
A(2,3,3) = 4
A(3,3,3) = 0
