Problem in Neural Network

When I try to run the code
img = edu_imgpreprocess(I);
for cnt = 1:50
bw2 = edu_imgcrop(img{cnt});
charvec = edu_imgresize(bw2);
out(:,cnt) = charvec;
end
P = out(:,1:40);
T = [eye(10) eye(10) eye(10) eye(10) ];
Ptest = out(:,41:50);
For 26 alphabets making a change in the code as follows:
img = edu_imgpreprocess(I);
for cnt = 1:26
bw2 = edu_imgcrop(img{cnt});
charvec = edu_imgresize(bw2);
out(:,cnt) = charvec;
end
P = out(:,1:20);
T = [eye(10) eye(10) eye(10) eye(10) ];
Ptest = out(:,21:26);
It gives me an error of
Error using rgb2gray>parse_inputs (line 81)
MAP must be a m x 3 array.
Error in rgb2gray (line 35)
X = parse_inputs(varargin{:});
Error in edu_imgpreprocess (line 3)
Igray = rgb2gray(I);
Error in char3 (line 8)
img = edu_imgpreprocess(I);
Kindly help please. Thanks.

I don't see any neural network functions. So why use neural network in the title?
can you share with us your code after modification?
@Mo'ath Al-Hayek probably not since @Mohammad has not been here in 9 years so he'll probably never see your message. Or if he does, he doesn't have the code anymore. You're best off just posting your own question in your own new discussion thread (not here).

If this is still a problem for you, what did you pass in for (the badly-named) I? Do a "whos I" before that line and say what is in the command window. Changes are it's not a regular, normal RGB image.
Replace this:
Igray = rgb2gray(I);
with this:
if ndims(I) == 3
Igray = rgb2gray(I);
else
Igray = I;
end
