choreo.NBodySyst.TT_params_to_action_grad#

NBodySyst.TT_params_to_action_grad(self, double[::1] params_mom_buf, TT)#

Profiles the computation of the gradient of the action with respect to parameters.

Parameters:

  • params_mom_buf (numpy.ndarray(shape = nparams, dtype = np.float64)) – Buffer of parameters.

  • TT (pyquickbench.TimeTrain) –

    Profiler object that records the following intermediate times:

    • start

    • memory

    • changevar_mom_pos

    • params_to_pos_slice

    • pos_slice_to_segmpos

    • segm_pos_to_pot_nrg_grad

    • segmpos_to_pos_slice_T

    • pos_slice_to_params

    • changevar_mom_pos_T

    • params_to_kin_nrg_grad_daxpy

Returns:

Gradient of the action with respect to parameters.

Return type:

numpy.ndarray(shape = nparams, dtype = np.float64)
