Consider the following function,f:
if x=0:
f(x)=0
else:
f(x)=sin(1/x)
how to formulate that as a Matlab M-File function?
thanks?

moh - you state that f is a function but perhaps it is an array instead? are you passing in x to this function and expect to get something returned? Is x an integer or real number? Please provide more details.

This works:
function output = f(x)
output = sin(1 ./ x);
% Zero out any values where x is exactly zero.
output(x == 0) = 0;
% Note, this works regardless if x is a scalar or a vector or matrix.
To call it, here is an example:
x = randi(5, 6, 6) - 1
output = f(x)
