How do I use files from file exchange?

114 views (last 30 days)
So I want to plot with 3 y axis and found some awesome work of people who shared them on file exchange.
How do I integrate them properly in my code ? Do I have to dl them and add them to same folder? If yes, how can I call them? Do I use their file name ?

Download the .zip files.
Decompress same.
The result will be a directory. Add that directory to your search path. Pathtool is a good tool for this purpose.
Save the modified search path, so the next time you get into MATLAB, it will remember them.

John's answer on this is good, and can be used even with older MATLAB.
With new-enough MATLAB, you also have the option of using Add-On Explorer. Look in the ribbon of the command window for Add-Ons and click there and select Get Add-Ons . Use the window that comes up (the Add-On Explorer) to search for topics of itnerest. Click on one of them to verify it is what you want. In the upper right there will be a button for Install if you want to add that contribution to your MATLAB.

Thanks to both of you!
From that point on I just call the function? Or do I have to use a special line first in my code to load up the files?

Rik is correct, that please do not treat a question as a thread, where you just keep adding answers to make a comment. Use comments for that.
But once a file is on your search path, then MATLAB can always use it. It will now see this function always as long as you have saved the search path. There is no need to include it, for example as Python would require to load the function.
The one thing you never want to do is to put such a function in the matlabroot directory, or in any of the MathWorks provided toolbox directories.
