Ramp Function
Usage
Ramp[x] gives x if x>=0 and 0 otherwise.
Basic examples
Evaluate numerically: In[1]:=Ramp[-1] Out[1]=0 In[2]:=Ramp[3.7] Out[2]=3.7 Plot over a subset of the reals: In[1]:=Plot[Ramp[x], {x, -2, 2}] Out[1]= Ramp is a piecewise function: In[1]:=PiecewiseExpand[Ramp[x]] Out[1]= piecewise | x | x>=0 0 | True
