I am needing to plot many things from a .mat file but do not want to copy and paste the same code 30 times. I am wanting to set a varible such as 'CylinderPressure' and call it later. This works for everything but plotting. How can I change the 'CylinderPressure' so whats in it (the varible in question) can be referenced in plotting. In the end I want to just change the var variable to change what I am plotting. I atached the code I want to modify. Any help would be greatly apreciated.
var = 'CylinderPressure';
hold on
load('march.mat', var)
plot(CylinderPressure)
load('Feb.mat', var)
plot(CylinderPressure)
title(var)
legend('march','feb')
hold off

Do NOT load directly into the workspace, always LOAD into an output variable (which is a scalar structure).
Then simply use this syntax:
var = 'CylinderPressure';
S1 = load('march.mat',var);
S2 = load('Feb.mat' ,var);
V1 = S1.(var);
V2 = S2.(var);
hold on
plot(V1)
plot(V2)
title(var)
legend('march','feb')
hold off
