nfeval.m

介绍了几个基于EKF扩展卡尔曼滤波的例子

function [functionValue] = nfeval(p,point)
% NFEVAL - evaluating the function of the nffunction object p
%
% p         ... object of the class nfExampleFunction
% point     ... vector value at whitch is the function evaluated

if length(point) ~= p.nvar
  error('Wrong number of input arguments');  
else    % return value of the function
  functionValue = [point(1)*point(2)+point(3);
                   point(2)+point(4)];
