Nonlinear least square optimization through parameter estimation using the unscented kalman filter in matlab

The following Matlab project contains the source code and Matlab examples used for nonlinear least square optimization through parameter estimation using the unscented kalman filter. The Kalman filter can be interpreted as a feedback approach to minimize the least equare error.

Implementations of kalman filter using both message passing algorithm and standard matrix operations in matlab

The following Matlab project contains the source code and Matlab examples used for implementations of kalman filter using both message passing algorithm and standard matrix operations. This is a demo of using message passing algorithm (belief propagation) to implement Kalman Filter.

Function evaluatealphabetaparam evaluates alpha and beta parameters for alpha-beta filter in matlab

The following Matlab project contains the source code and Matlab examples used for function evaluatealphabetaparam evaluates alpha and beta parameters for alpha-beta filter . This function evaluates alpha and beta parameters for alpha-beta filter so that the alpha-beta filter becomes a steady-state Kalman filter.

Function evalabgparam evaluates the best stable values for an alpha-beta-gamma filter in matlab

The following Matlab project contains the source code and Matlab examples used for function evalabgparam evaluates the best stable values for an alpha-beta-gamma filter . This function evaluates alpha, beta and gamma parameters and also test its stability. These parameters can make alpha-beta-gamma filter act like a steady-state Kalman filter.

Kalman Filter Matlab Code

Kalman filter is an algorithm that uses a series of measurements observed over time, containing noise (random variations) and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone.
