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)

Assume f(x) is a continuous time signal

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.

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.
