Vadim,
I don't obtain that result, either in a Plot or in a Table.
h[x_] := 0 /; x < 0
h[x_] := x /; x >= 0
Table[h[x], {x, -1, 1, 0.25}]
{0, 0, 0, 0, 0., 0.25, 0.5, 0.75, 1.}

Hello,
I am defining a function:
h[x_]:=0/;x<0
h[x_]:=x/;x>=0
When I try to plot the function:
Plot[h[x],{x,-1,1}]
I see that it's defined as h[x_]:=x on all values, not only positive ones.
What am I missing here?
Thanks.
Vadim.
