I have a small project and don't know how to write and plot the following functions in MATLAB:

f1(t) = tu(t) - tu(t-1)

f2(t) = 10{e}^{-4t }

Could someone lend me a hand here or send me a tutorial? Thanks.
 

Try the lecture notes here;

For the second function, f2(t) = 10{e}^{-4t }.
Use the following code:
First of all, you need to define the limits of the variable 't'. Like t goes from 0 to 1 or whatever your choice is.
I took the limits for t from 0.1 to 2, with increments of 0.1

t=0.1:0.1:2;

f=10*exp(-4*t);
plot(t,f);
 
Thanks for your help! Very useful both replies.
