you have to load variables from the mat file to your worksapce, then you can plot them or process them:
load matfileName

clear all
worksapce % make sure wirkspace panel is showing
load fullfilename % check out workspace panel for the variables loaded
% It might be vectors containing independent and dependent variables
% or a single matrix having different variables in differenet columns
t = yourArray(:,1) % lets say it's a matrix
x = yourArray(:,2)
plot(t,x)
