get_angle

ssapy.utils.get_angle(a, b, c)

Calculate the angle between two vectors where b is the vertex of the angle.

This function computes the angle between vectors ba and bc, where b is the vertex and a and c are the endpoints of the angle.

Parameters:

a(n, 3) numpy.ndarray

Array of coordinates representing the first vector.

b(n, 3) numpy.ndarray

Array of coordinates representing the vertex of the angle.

c(n, 3) numpy.ndarray

Array of coordinates representing the second vector.

Returns:

numpy.ndarray

Array of angles (in radians) between the vectors ba and bc.

Notes:

• The function handles multiple vectors by using broadcasting.

• The angle is calculated using the dot product formula and the arccosine function.

Example:

>>> a = np.array([[1, 0, 0]])
>>> b = np.array([[0, 0, 0]])
>>> c = np.array([[0, 1, 0]])
>>> get_angle(a, b, c)
array([1.57079633])
