Generating Gaussian filters in a loop

I want to filter an image with generated in a loop Gaussian filters and compare results.

*Error: In an assignment A(I) = B, the number of elements in B and I must be the same.

Error in PL8ex2 (line 19) fg(i) = fspecial('gaussian', h, s);*

org = imread('leftretina.tif');
%grey = rgb2gray(org);

%h = fspecial('gaussian', hsize, sigma) returns a rotationally symmetric 
%Gaussian lowpass filter of size hsize with standard deviation sigma 
%(positive). hsize can be a vector specifying the number of rows and 
%columns in h, or it can be a scalar, in which case h is a square matrix. 
%The default value for hsize is [3 3]; the default value for sigma is 0.5. 
%Not recommended. Use imgaussfilt or imguassfilt3 instead.  

LG = zeros(1,6);
fg = zeros(1,6);
hsize = [3 5 7 9 11 20];
sigma = [0.5 0.8 1 1.5 2 3];
title = zeros(1,6);
for i=1:6
h=hsize(i);
s=sigma(i);
fg(i) = fspecial('gaussian', h, s);
LG(i) = imfilter(org,fg(i)); % Gaussian filter
title(i) = sprintf('Gaussian filter of size %d and sd %,2f.',h, s);
end

%Graphics
subplot(2,3,1); imshow(LG(1));
title(title(1),'FontSize',12);
subplot(2,3,2); imshow(LG(2));
title(title(2),'FontSize',12);
subplot(2,3,3); imshow(LG(3));
title(title(3),'FontSize',12);
subplot(2,3,4); imshow(LG(4));
title(title(4),'FontSize',12);
subplot(2,3,5); imshow(LG(5));
title(title(5),'FontSize',12);
subplot(2,3,6); imshow(LG(6));
title(title(6)','FontSize',12);

Thank you in advance.
