Hello,
I am unable to use my image processing toolbox functions. I have the add-on installed, and it works on my laptop so I know I have the correct liscence avaliable.

I find someone with your name who is a masters student. Are you using an Education license, and not a Student license?

Type
>> ver
on the command line. What do you see? (Edit out your license number before pasting here.)

When you use "ver" does "License number:" say "Student" ?

If youi run this code, what do you see in the command window?
% Check that user has the specified Toolbox installed and licensed.
hasLicenseForToolbox = license('test', 'image_toolbox'); % Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Image_Acquisition_Toolbox'); % Check for Image Acquisition Toolbox.
% hasLicenseForToolbox = license('test', 'Statistics_Toolbox'); % Check for Statistics and Machine Learning Toolbox.
% hasLicenseForToolbox = license('test', 'Signal_Toolbox'); % Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Video_and_Image_Blockset'); % Check for Computer Vision System Toolbox.
% hasLicenseForToolbox = license('test', 'Neural_Network_Toolbox'); % Check for Deep Learning Toolbox.
if ~hasLicenseForToolbox
% User does not have the toolbox installed, or if it is, there is no available license for it.
% For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
ver % List what toolboxes the user has licenses available for.
message = sprintf('Sorry, but you do not seem to have the Image Processing Toolbox.\nDo you want to try to continue anyway?');
reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
if strcmpi(reply, 'No')
% User said No, so exit.
return;
end
end

Then it will work. What evidence do you have that it's not working?

For example on the Machine Learning and Statistics toolbox if I try to use corr() it says function not found:

What shows up if you use
license('test', 'Statistics_Toolbox')
if it shows 0 then you do not have a license for the toolbox; if it shows 1 then you might need to do
restoredefaultpath; rehash toolboxcache

That screenshot you posted does not show corr() is not working. Please show a screenshot of the error.
Do you have an individual license, or a shared (pooled) license? You may have the toolbox installed but if you have a shared license and all the licenses for that particular toolbox are checked out then it will tell you that you don't have a license.
Your best bet is to call them tomorrow and ask for free installation help.
