Here is an example where I have supplied some arbitrary values for P,N, phi and omega. You can modify with the values you actually want to use
P = 5
N = 2
phi = pi/3
omega = pi/4
t = linspace(0,20); %put your final time here
i = complex(0,1)
z = P*exp(i*phi)*exp(i*omega*t) + N*exp(i*phi)*exp(-i*omega*t)

You can also use 1i to represent a complex value and do it like this
P = 5
N = 2
phi = pi/3
omega = pi/4
t = linspace(0,20); %put your final time here
z = P*exp(1i*phi)*exp(1i*omega*t) + N*exp(1i*phi)*exp(-1i*omega*t)

Writing the equation is rather straightforward. You just need to decide what variable names you want to use. Here's one way.
z = P*exp(phi*1i)*exp(w*t*1i) + N*exp(phi*1i)*exp(-w*t*1i)
I suggest going through MATLAB Onramp will enable you to not only write the equation yourself, but actually use it to calculate values for z.
