How to solve "Transpose on ND array is not defined. Use PERMUTE instead."

lena = double(imread('lena.tif'));
figure(6);
imshow(lena)
y_LenaHalf = double(imread('lena_half.tif'));
figure(7);
imshow(y_LenaHalf)
x2 = 1:256;
xi_2 = 1:(255/511):256;
yi_2 = interp1(x2, y_LenaHalf, xi_2);
yi2_2 = interp1(x2, yi_2.', xi_2).';
figure(8);
imshow(uint8(yi2_2))
SE2 = (lena - yi2_2).^2;
MSE2 = mean(mean(SE2));

I want to enlarge photo 'lena' using interp1, but i got an issue.

Error using .' Transpose on ND array is not defined. Use PERMUTE instead.

Error in week9_lectorial (line 44) yi2_2 = interp1(x2, yi_2.', xi_2).';

A = rand(2,3,3) ;
A'    % throws error

So, you cannot transpose a 3D matrix, striaght away. Check this:

[m,n,p] = size(A) ;
iwant = zeros(n,m,p) ;
for i = 1:p
   iwant(:,:,i) = A(:,:,i)' ;
end

Then how can I solve my issure straight away in my code?
