erreur in imshow ?

Hello everyone. When I try to run my code I have this error in using imshow. I don't know why I'm getting this problem.

This is my code

I = imread('cameraman.tif');
I2  = imresize(rgb2gray(imread('onion.png')),[size(I,1),size(I,2)]);
ImLength = size(I,1);
% Create image large enough to encapsulate both of them
Iend = uint8(zeros(2*ImLength,2*ImLength));
Iend(1:ImLength,1:ImLength) = I; % First image
Iend(ImLength+1:end,1:ImLength) = I2; % Second image
Iend(1:ImLength,ImLength+1:end) = I2; % Second image
Iend(ImLength+1:end,ImLength+1:end) = I; % First image
figure,imshow(Iend)

This is the error message

Attempt to execute SCRIPT image as a function:

C:\Users\hp\Desktop\knn\image.m

Error in images.internal.basicImageDisplay (line 24)

hh = image(cdata, ...

Error in imshow (line 321)

hh = images.internal.basicImageDisplay(fig_handle,ax_handle,...

Error in image (line 26)

figure,imshow(Iend)

#No Error

I = imread('cameraman.tif');
I2  = imresize(rgb2gray(imread('onion.png')),[size(I,1),size(I,2)]);
ImLength = size(I,1);
% Create image large enough to encapsulate both of them
Iend = uint8(zeros(2*ImLength,2*ImLength));
Iend(1:ImLength,1:ImLength) = I; % First image
Iend(ImLength+1:end,1:ImLength) = I2; % Second image
Iend(1:ImLength,ImLength+1:end) = I2; % Second image
Iend(ImLength+1:end,ImLength+1:end) = I; % First image
figure,imshow(Iend)

This is a classic, perfect example of why it's not good to name your scripts or variables after built-in functions. Since you called your script image.m, it tried to use that (your script) when the imshow() function tries to use the built-in image() function. Rename your script to something else so it doesn't conflict with any built-in function names, like image, or sum, min, max, plot, etc. which are common script names people try to use and which cause problems.
