Hi Tufan,
Instead of using the heaviside() function, you can define your own function with a simple if elseif ladder. If the parameter is less than 0, you can return 0, at equal to 0, return 0.5 and greater than 0 return 1.
Hope it helps.

Hi @GundaBerunda
Sure @Tufan can learn to write a custom function. However, the heaviside() function also uses the if-else conditional statement. If you can write a conditional-free simple code that works similarly as the Heaviside function, then it will benefit the community.

Hi @Sam Chak
One simple approach without if else which I can think of is:
out=(x>0)+0.5*(x==0)
where out is the result, and x is the input
