Would you like to be able to specify a piecewise
function? For example, piecewise_eval can do this:

x < -5, y = 2
-5 <= x < 0, y = sin(x)
0 <= x < 2, y = x.^2
2 <= x < 3, y = 6
3 <= x, y = inf

y = piecewise_eval(-10:10,[-5 0 2 3], ...
{2,'sin(x)','x.^2',6,inf})

Plot a top hat function with ezplot?
ezplot(@(x) piecewise_eval(x,[0 1],{0 1 0}),[-1 2])
