MATLAB Function declaration

I am trying to convert the function below to Python, but I am not sure what is going on. 

function [ray]=create_ray(point1,direction)
ray.direction.x=direction.x;
ray.coefficients.x=(point1.x);
ray.direction.y=direction.y;
ray.coefficients.y=(point1.y);
ray.direction.z=direction.z;
ray.coefficients.z=(point1.z);

I know that it returns an array, ray, but what exactly is it doing with direction and coefficients? Could someone please explain to me what is going on. Any help would be greatly appreciated.

ray is the return value. The python version will be

    def create_ray(point1, direction):
        ...
        return ray

where ray is function [ray]=create_ray(point1,direction) in the Matlab code.

BTW, the ray would be defined by class in Python. So the final code can be

class Direction(object):
    x, y, z = None, None, None

class Coefficients(object):
    x, y, z = None, None, None

class Ray(object):
    direction = Direction()
    coefficients = Coefficients()

def create_ray(point1, direction):
    ray = Ray()
    ray.direction.x = direction.x;
    ray.coefficients.x = point1.x;
    ray.direction.y = direction.y;
    ray.coefficients.y = point1.y;
    ray.direction.z = direction.z;
    ray.coefficients.z = point1.z;
    return ray
