Do you know why it doesnt plot on MATLAB itself?
I can't see how MATLAB is configured on your computer. Don't you get an error message ? Maybe you don't have the Signal Processing Toolbox licenced and/or installed which is necessary for using "dct".

Hi Liam,
This is the default behaviour for MATLAB scripts or '.m' files. If you want the figure to show up in line with the code, you can consider using a MATLAB live script instead.
