Not to be used with STEP format...  the step function for equations...

Anyone have a good example of using it?

The STEP(a, x1, y1, x2, y2) function returns a smooth step function applied to an expression a for time or for a result. The smooth cubic function starts rising at (x1,y1) on the horizontal axis, and levels off at (x2,y2). Use this function in expressions for forces or motors.

Format

STEP(a, x1, y1, x2, y2)

Arguments

aSelect any valid result from the list, or enter time.
x1The point on the horizontal axis at which the step begins to rise.
y1The value of the step function before the point x1.
x2The point on the horizontal axis at which the step levels off.
y2The value of the step function at the leveling off point x2.
