tmdsimpy.utils.continuation.continuation_save

tmdsimpy.utils.continuation.continuation_save(XlamP, dirP_prev, fname)

Saves continuation data to a file.

Saves continuation variables. Saved output will 2D arrays with the same names as inputs here. Each row of output will correspond to a single solution point.

Parameters:

XlamP(N+1,) numpy.ndarray

Solution at the current step in physical coordinates (including continuation parameter).

dirP_prev(N+1,) numpy.ndarray

Direction for prediction from previous step to this step. Can be used to get slope of solution at previous point w.r.t. lam by dividing dirP / dirP[-1]

fnamestr

Filename to save variables to. Should have file extension of .npz

Returns:

None.

Examples

Define a callback function handle to pass to tmdsimpy.Continuation as

>>> callback_fun = lambda XlamP, dirP_prev : continuation_save(XlamP, 
...                                            dirP_prev, 'saved_data.npz')
