Function min_plus_convolution_concave_both 

pub fn min_plus_convolution_concave_both<T>(a: &[T], b: &[T]) -> Vec<T>
where
    T: Signed,

Computes convolution of two concave inputs from antidiagonal endpoints.

The running time is O(n + m).

Panics

Panics unless both inputs are finite and concave.
