extract from different .mat file to plot

I have a bunch of data in abc_001a01.mat,abc_002a01.mat,abc_001b02.mat and a few more which start with abc. I would like to extract variable N from each .mat and plot it into a graph without manually key in load('abc_001a01.mat'); load('abc_002a01.mat') and so on. Can anyone give me a clu how to start the coding? I am a beginner so please make it easy to understand

Thanks Dav

% all your mat-files starting with abc

f=dir('abc*.mat')
filename={f.name}   % all your mat-files starting with abc

To read a mat-file

k=1
N=load(filename{k})
N=N.N
