In a-parton/CTStepTurn: Fitting the continuous-time step-and-turn movement model

Description

calc_dist_true_locs_backward returns the distribution of a set of locations, given step distribution and actual bearings, in reverse-time.

Usage

calc_dist_true_locs_backward(start_loc, fixed_index, bearings, step_dist)

Arguments

start_loc	Vector (length 2) of the x,y ending position of the section to update.
fixed_index	Vector (variable length, at least 1) of the index points on the section where a fixed location is (will always include the initial location).
bearings	Vector (variable length) of the actual bearings on the section.
step_dist	List with components: mean Vector of the mean step lengths on the section. covar Square matrix of the covariances between the steps on the section.

Value

List with components:

A

Linear constraint matrix.

loc_mean

Vector of location means (arranged as x_1,y_1,x_2,...).

loc_covar

Square matrix of location covariances.

loc_step_covar

Matrix of covariances between the steps and the locations.
