Hi,
I have an array sized n*3. Each three-component is a 3D position. Given
another 3D position, how is the distance between it and every
three-component in the array found with NumPy?
So, for example, if the array is:
[[0,0,0],[0,1,0],[0,0,3]]
And the position is:
[0,4,0]
I need this array out:
[4,3,5]
(Just a simple Pythagorean Distance Formula)
Ideas?
Thanks,
Ian
