dist_matrix

nrv.nmod.utils.dist_matrix(X: tuple[ndarray, ndarray, ndarray]) → ndarray[source]

Get a matrix containing the distance of three array containg the position and radius of various circles.

Note

For n circles the matrix return is of dimension (n,n) and the index (i,j) contains the distance between the ith and jth circles.

Tip

By definition, the returned matrix is symetric and with a zero diagonal.

Parameters:

X (tuple[np.ndarray, np.ndarray, np.ndarray]) –

Tuple of 1D-ndarray of same lengh containing the respectively:

  • the y position of each circle

  • the z position of each circle

  • the radius of each circle

Return type:

np.ndarray
