atompy.Vector.keep_where# Vector.keep_where(mask)[source]# Keep every vector i where mask[i] == True Parameters: masknumpy.ndarray, shape (len(self),)Array of booleans. Returns: Vector Examples >>> vec = Vector([[1, 2, 3], [4, 5, 6]]) [[1. 2. 3.] [4. 5. 6.]] >>> vec.keep_where(vec.z == 3) [[1. 2. 3.]]
