Visual Kalman Filter - Version 2.8 "Visual Kalman Filter " is a visual math tool to simulate Kalman filter for linear or nonlinear system. Only three steps you need do,and you'll get the curve and the estimated results.. Its price is only $49.90.The Kalman filter is a set of mathematical equations that provides an efficient computational (recursive) means to estimate the state of a process, in a way that minimizesthe mean of the squared error. The filter is very powerful in several aspects: it supports estimations of past, present, and even future states, and it can do so even when the precise nature of the modeled system is unknown.'Visual Kalman Filter' provides a visual method to estimate the state of a process. The users need not install matlab, and there are only three steps to
