Create An Array That Contains All the Values of F(x)? Help!

I have a function f(x) that equals x if x < 1 and x^2 elsewhere.

How would I go about putting all the values of f(x) into another array, named y, for example?

[Steven]

If this helps x = linspace(-1,2,100).

Answer 1

[Jan]

And to be complete:

y = x.^2;
y(x < 1) = x(x < 1);

Answer 2

[James Tursa]

y = x;

y(y<1) = 1;

y = y.*x;

Answer 3

[Azzi Abdelmalek]

x=-5:5
y=(x<1).*x+(x>=1).*x.^2
