[RFC]: Bray-Curtis distance between two strided arrays #834
Description
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.
