My approach to these problems is to take advantage of MATLAB’s logical vectors.
So for example, if I wanted to construct a function that was +1 for x-values between -1 and 0, and -1 for x-values between 1 and 2, I would do this —
f = @(x) 1.*((x>=-1) & (x<=0)) + (-1).*((x>=1) & (x<=2));
x = linspace(-3, 3);
plot(x, f(x))
ylim([-1 1]*1.1)
You can also use an if block.
