I want to plot a discontinuous step surface. I entered this plot statement:
Plot3D[{if[x > 0, x = 0, x = 1]}, {x, 2, -2}, {y, 2, -2}]
All I get is an empty box. What went wrong?
Try with If and not if But may be better to use Piecewise
If
if
Piecewise
Clear[x, y] f[x_] := Piecewise[{{0, x > 0}, {1, True}}]; Plot3D[f[x], {x, 2, -2}, {y, 2, -2}, Exclusions -> None]
Perfect! Thank you Nasser Abbasi!
The Problem is nothing but, you have used small "i" instead of capital "I" for If function. Its working well.
