How would you go about synthesising a discrete signal given by the expression x[n]=9cos(1.7nT+3.74) for 0<=n<=1654, when the sampling period is 0.544? The manner of signal is much different from my last question.
Thank you in advance.

Ran in:
You would vectorize. For example,
format long g
t = 1 : 10
t = 1×10
1 2 3 4 5 6 7 8 9 10
y = exp(-t/sqrt(7)+sqrt(5))
y = 1×10
