Use the vectorize (link) function.
The only change you temporatily need to make is to create your function as a character vector by putting single quotes (') around it first, then removing them from the vectorize output.
Example —
f = exp(-0.1*t) * sin(2*pi*t);
fv = vectorize('exp(-0.1*t) * sin(2*pi*t)')
fv =
'exp(-0.1.*t) .* sin(2.*pi.*t)'
You then have to manually edit your expression to put it back as a valid expression. That simply means removing the single quotes:
f = exp(-0.1.*t) .* sin(2.*pi.*t)
and your expression is vectorized, ready for your linspace arguments!
EDIT — Corrected typographical errors.

You have two possibilities here:
  1. In the text file, you replace * by .* and / by ./ in all the document (there is an option in the replace to replace all).
  2. If you have it like a function and want to do it by programming, you can overload the funtion mtimes and mrdivide by times and rdivide as:
function c = mtimes(a,b), c = times(a,b); end
function c = mrdivide(a,b), c = rdivide(a,b); end
You can add this to the end of your file or to your folder.
By preference, always do the first method, as overloading operators is not a good practice unless you try to ofuscate your code, but I have found some moments where it's the only way
