Hi,all

Here is an application of step fuction:

C=a*step(-x)

So c=0 when x>0; and c=a when x<0.

However, when x=0, I will get c=0.5a

I want to let c=0 when x=0, how can I do that?

Thanks!

John

The CFX step(x) function gives:

0 when X < 0 0.5 when X = 0 1.0 when X > 0

step(step(x)-0.6) should give

0 when x < 0 {step(-0.6) = 0} 0 when x=0 {step(-0.1) = 0} 1 when x > 0 {step( 0.4) = 1}

Great idea, Jeff

Thanks!
