That is a function defined as:

f(x) = -1 if x is negative

f(x) = 0 if x is zero

f(x) = 1 if x is positive

In other words, a function that basically distinguishes whether the input is positive, negative, or zero.

Is signum function differentiable?

The signum function, also known as the sign function, is not differentiable at zero. This is because the derivative of the signum function is not defined at zero due to a sharp corner or discontinuity at that point. In mathematical terms, the signum function has a derivative of zero for all values except at zero, where it is undefined. Therefore, the signum function is not differentiable at zero.
