How can i write this function in matlab?

I want to plot this function

x(t) = 4(t+1)[u(t+1)-u(t)] + (4-2t)[u(t)-u(t-2)]
y= inline('4*g(t+1).*(u(t+1>=0)-u(t>=0)','t' )

I want to write x(t) in matlab , was my solution y for part of the equation correct or not?

inline is recommended against, and has been for close to 20 years. You should use anonymous functions instead.

No, u(t) represents the unit step function. You should use heaviside(t) but watch out for the value at heaviside(0)

You can also replace u(t) with double(t>=0)
