sponge.function.calc_angle
- sponge.function.calc_angle(position_a: Tensor, position_b: Tensor, position_c: Tensor, pbc_box: Tensor = None, keepdims: bool = False)[source]
Compute angle formed by three positions \(A\), \(B\) and \(C\) with or without periodic boundary condition.
- Parameters
position_a (Tensor) – Tensor of shape \((..., D)\) . Data type is float. D means spatial dimension of the simulation system. Usually is 3. Position coordinate of point \(A\).
position_b (Tensor) – Tensor of shape \((..., D)\) . Data type is float. Position coordinate of point \(B\).
position_c (Tensor) – Tensor of shape \((..., D)\) . Data type is float. Position coordinate of point \(C\).
pbc_box (Tensor) – Tensor of shape \((D)\) or \((B, D)\) . Data type is float. B means batchsize, i.e. number of walkers in simulation Size of PBC box \(\vec{L}\). Default:
None.keepdims (bool) – If this is set to True, the last axis will be left in the result as dimensions with size one. Default:
False.
- Returns
angle (Tensor), a tensor of shape \((...)\) or \((..., 1)\). Data type is float.
