Hi everyone,
I am new to Matlab and trying to understand export_fig function. When I use it I got this error: Undefined function 'export_fig' for input arguments of type 'char'.
What should I do to fix it?
Thank you

In an .m-file on your Matlab path. For example in your current folder.

export_fig is not part of any MathWorks toolbox. It is a submission on the MATLAB Central File Exchange. You can install it using the Add-Ons button on the Home tab of the toolstrip or by downloading it and setting it up manually.

Either copy export_fig to the path, which contains your M-files - this might be the userpath. Or Store it in an own folder, maybe containing other tools downloaded from the FEX also. Then add the folder to your path (this is the list of folders, Matlab searches in for functions:
addpath('C:\TheFolder\WichContains\TheMFile\', '-end')
You can save the path for future Matlab sessions also:
savepath
Adding and saving the path can be done by
pathtool
also, which can be started through the menubar also: "Set Path".
