Hi, I have a list of x/y coordinates. Is there an easy way to subtract a function (y = f(x)) from all y data? Thanks a lot!

Isn't this trivial?
f = @cos;
x = linspace(0, 2*pi, 100);
y = sin(x);
y2 = y - f(x);
or any other function instead of cos as long as it replies a vector with the same dimensions as the input.

I was curious whether there was something quick like find(y-(@(x))). Thanks anyway.
