Function argmin_testfunctions::rosenbrock_ab_derivative_const

pub fn rosenbrock_ab_derivative_const<const N: usize, T>(
    param: &[T; N],
    a: T,
    b: T,
) -> [T; N]
where
    T: Float + FromPrimitive + AddAssign,

Derivative of the multidimensional Rosenbrock test function

The parameters a and b can be chosen freely.

This is the const generics version, which requires the number of parameters to be known at compile time.
