Summary0000313: Performance improvements: estspf
DescriptionProfile estspf and attempt to improve performance, particularly with the parallel processing toolbox. It may be that estspf could reap big gains by parallelizing the sigma points.

Issue 0000274 improved the parallel processing for estseq.

Replacing calls to slow unnecessary functions will boost efficiency, particularly replacing 'repmat' calls.

On the user side, setting up the measurement function to take in a vector of states and returing a vector of measurements is beneficial. Discretizing the calls to the measurement function is unproductive if not necessary.

If the dynamics model can also handle a vector of states, then it could take in all the sigma points at once. 'jatForces' appear capable of handling this situation, however 'integ' would need some work. This may represent the largest possible gain in efficiency.
