#86: check matrix power used in forecast --------------------------+------------------------------------------------- Reporter: michel | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Core M-files | Version: Keywords: | --------------------------+------------------------------------------------- taking large matrix power in forecast step of the Kalman smoother routines is expensive, but probably more accurate than recursive multiplications. - investigate more accuracy issue - factorise matrix decomposition for matrix power
