How do I sample an aperiodic signal ?

my code goes like:

x=input('enter x co-ordinates')

y=input('enter y co-ordinates')

f=input('enter sampling frequency')

%function f(x)=

plot(x,y)

How do i sample f(x) at t=min(x):1/f:max(x)

[Kevin Bobby]

Assume f(x) is a continuous time signal

[Star Strider]

It seems that the function is defined for ‘t’ so it would exist as ‘f(t)’ and sampled at whatever the elements of ‘t’ are (at increments of ‘1/f’). Whether it is periodic is likely irrelevant if the objective is simply to plot it.

[Sai Charan Sampara]

Sampling a signal is only a method of changing a continuous time signal into a discrete time signal. It does not depend on the properties of the signal ,that is it being periodic or aperiodic. If the sampling frequency is fs then a sample can be taken at every 1/fs time interval.
