[RFC]: Bray-Curtis distance between two strided arrays

[Planeshifter]

Description

This RFC proposes adding a function to calculate the Bray-Curtis distance between two strided arrays.

Package: @stdlib/math/strided/distances/braycurtis

The function should have the following signature braycurtis( N, x, strideX, y, strideY ).

• N: Number of elements
• x: First array
• strideX: Stride for the first array
• y: Second array
• strideY: Stride for the second array

The function should return the Bray-Curtis distance between the two arrays. It is calculated by

d = sum( |x_i - y_i| ) / sum( |x_i + y_i| )

where x_i and y_i are corresponding elements from the two arrays.
