How to plot a function that has a parameter in the interval?

Hello, I am new to MATLAB. I have a piecewise function as follows.

How do I plot the graph of such a function? Any help would be appreciated, thank you!

Using the Symbolic Math Toolbox (if you have it):

syms t

a=1;

f=piecewise(0<t & t<a, exp(t), t>=a, 2*exp(t));

fplot(f,[0,2*a])

One possibility:

a=1;

f=@(t) exp(t).*(0<t & t<a)  + 2*exp(t).*(a<=t);

fplot(f,[0,2*a])
