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)
