compute_outer function

Computes distance on all possible combinations

Computes the distance between all combination of elements in two vector. a is vector of size n, and b is a vector of size m, the result, will be a matrix of size(n,m)

compute_outer(a, b, op)

Arguments

• a: first vector (size n)
• b: second vector (size m)
• op: operator (e.g., '-', '+', '/', ...)

Returns

A n by m matrix that includes abs difference between elements of vector a and b.
