Hi all,
I have written this code but when I run the code it gives the error
"Undefined function or variable imageX"
It is not my first time writing a code and I have other codes working properly except this one. Could someone help me figure out the problem?
here is the code I wrote:
function imageOut = imageX(imageIn,object);
jpgImage = imread(imageIn);
spaceRow = size(object,1)-size(jpgImage,1);
spaceAbove = round(spaceRow/2);
spaceBelow = spaceRow - spaceAbove;
jpgImage1 = [255.*ones(spaceAbove,size(jpgImage,2),size(jpgImage,3));jpgImage;255.*ones(spaceBelow,size(jpgImage,2),size(jpgImage,3))];
spaceColumn = size(object,2)-size(jpgImage,2);
spaceRight = round(spaceColumn/2);
spaceLeft = spaceColumn - spaceRight;
imageOut = [255.*ones(size(jpgImage1,1),spaceLeft,size(jpgImage,3)),jpgImage1,255.*ones(size(jpgImage1,1),spaceRight,size(jpgImage,3))];
imwrite(imageOut,'imageOut.jpg');
end

To put 255 around your image, why not use padarray()?

Since it's a function you can't actually run it by pressing F9 or the green arrow. You have to call it from the command window.
In this case it would be something like:
whatever_your_file_name_is(Input_for_imageIn,Input_for_object)
and hopefully that should work, let me know if it doesn't
Best of luck

Although it is true that you cannot just press F9 or the green arrow to run the code successfully, the error message would have been different in such a case: it would have been an error about an undefined input value rather than an error about the function not being found.
