Synthesising a different kind of discrete signal

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.

What is T?

The expression appears to be like π/2 nT + π + 0.6

T is the sampling period, 0.544.

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
