Documentation

User Manual

Installation

To install type:

$ pip install combineArrays

Usage of replicate_arrays( a, y, length_a, n)

from combineArrays import replicate_arrays

Parameters

Input parameters:

a: array to be replicated, float
n: num replications, int64

Output parameters:

y: replicated array of length n_times * length_array, float

Usage of calc_distance( a_x_u, a_y_u, b_x, b_y, dist, num_u, num_b)

from combineArrays import calc_distance

Parameters

Input parameters:

a_x_u, a_y_u: arrays of length num_u, float
b_x, b_y: arrays of length num_b, float

Output parameters:

dist: array of size U*B of pairwise distances arranged as [d_u1b1, d_u1b2, d_u2b1, d_u2b2, d_u3b1, d_u3b2], float

Usage of centroid_aux( a_demand, ov_allocation_u_b, a_coordinate_u, coo_b)

from combineArrays import centroid_aux

Parameters

Input parameters:

demand: array of length num_u, float
allocation: array of length num_u * num_b, float
coordinate: array of length num_u, float

Output parameters:

coo_b : array of length num_b, float
