TSForwardSetSensitivities#
Sets the initial value of the trajectory sensitivities of solution w.r.t. the problem parameters and initial values.
Synopsis#
#include "petscts.h"
PetscErrorCode TSForwardSetSensitivities(TS ts, PetscInt nump, Mat Smat)
Logically Collective on TS
Input Parameters#
ts - the TS context obtained from TSCreate()
nump - number of parameters
Smat - sensitivities with respect to the parameters, the number of entries in these vectors is the same as the number of parameters
Notes#
Forward sensitivity is also called ‘trajectory sensitivity’ in some fields such as power systems. This function turns on a flag to trigger TSSolve() to compute forward sensitivities automatically. You must call this function before TSSolve(). The entries in the sensitivity matrix must be correctly initialized with the values S = dy/dp|startingtime.
