How do I change the font size of the labels in my legend? For example, how do I make the font size of the ‘One’, ‘Two’, ‘Three’, ‘Four’ labels bigger in my plot?

You can change the font size for a MATLAB legend by setting the 'FontSize' property of the Legend object.
For example, plot four lines. Create a legend and assign the Legend object to the variable 'lgd'. Then, use dot notation to access the 'FontSize' property and set the value to 14 points.
lgd = legend('One','Two','Three','Four');
lgd.FontSize = 14;
Alternatively, you can specify the 'FontSize' property using a name-value pair argument in the 'legend' command. When including name-value pair arguments, include the legend labels in a cell array. For example:

ali jebeli: which MATLAB version are you using?

I had the same problem, I am using version 2016b. The Legend box became bigger but the text rermains small.
What can I do?
edit: I needed to change manually, very frustrating. Unconvenient for such an expensive software.

This problem sounds like the one I am experiencing now. After I changed the setting I saved the figure as a .fig, closed the figure window, then loaded the figure again (by simply double clicking it). After the figure reloaded my legend font changes were implemented.

Here you go :
h = legend('x','y','z');

Hi I am using 2015b. "h= legend('x','y','z'); set(h,'FontSize',12); worked really well and it is good when we need the axes' labels in bigger sizes However it took a very long time to proceed for such two simple lines! please advise

You need to pass the path of the directory containing the data to EigenfaceCore . See the example.m file for example.
