Compute a smooth approximation of the maximum of two values.
This function returns a value close to max(a, b), but is differentiable everywhere.
The eps parameter controls the smoothness: larger values make the transition smoother.
- Parameters:
a (float) – The first value.
b (float) – The second value.
eps (float) – Smoothing parameter (should be small and positive).
- Returns:
A smooth approximation of max(a, b).
- Return type:
float
