国外牛人写的经典的粒子滤波的源代码。很适合入门者研究。有详细的注释。(Classic foreign cattle were written the source code for Particle Filtering. Very suitable for beginners of. Detailed notes.)

Default constructor, for use by subclasses.

利用modmap函数对ask、fsk、msk以及psk进行使用说明(use modmap function ask, fsk, msk and psk for use)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization algorithm and Matlab, very simple.)

关于粒子滤波的MATLAB源代码，实现了目标跟踪的效果~直接运行，有图像，希望大家喜欢。(On the particle filter MATLAB source code, to achieve the target tracking results ~ direct run, there is the image, hope you like.)

说明：  插值与拟合程序.matlab学习毕业设计必用.(Interpolation and fitting procedures. Matlab graduate study design must be used.)

the fuction performs thresholding to the eye images. this function can be used in implementing daugman algo for iris localization.

汽车高斯曲面拟合 --- 2程序，以适应到表面二维高斯： 子= A *的进出口（ -（（西为X0）^2/2/sigmax^2 +（艺Y0的）^2/2/sigmay^ 2）。。）+ b的 这些例程是自动在某种意义上说，他们并不需要出发对模型参数的猜测规范。 autoGaussianSurfML（十一，彝，子）适合通过对模型参数的最大似然（最小二乘）。它首先计算了该模型在许多可能的参数值，然后选择最佳质量设置和细化与lsqcurvefit它。 autoGaussianSurfGS（十一，彝，紫）的估计，通过指定数据的贝叶斯生成模型，然后采取通过从模型吉布斯抽样样本后ofthis模型参数。这种(Auto Gaussian Surface fit --- 2 routines to fit a 2D Gaussian to a surface: zi = a*exp(-((xi-x0).^2/2/sigmax^2+ (yi-y0).^2/2/sigmay^2))+ b The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. autoGaussianSurfML(xi,yi,zi) fits the model parameters through maximum likelihood(least-squares). It first evaluates the quality of the model at many possible values of the parameters then chooses the best set and refines it with lsqcurvefit. autoGaussianSurfGS(xi,yi,zi) estimates the model parameters by specifying a Bayesian generative model for the data, then taking samples from the posterior ofthis model through Gibbs sampling. This method is insensitive to local minimain posterior and gives meaningful error bars (Bayesian confidence intervals))

产生轨迹，可以产生直线轨迹，直线加速轨迹，转弯轨迹，得到的物体真实运动的轨迹，并且显示出来。(Have a track, you can have a straight-line trajectory, a straight-line speed up the track, turning the track has been real movement of the object trajectory, and displayed.)

四旋翼飞行器在MATLAB下的建模程序，非常好，非常真实(Four-rotor aircraft under the MATLAB modeling program, very good, very durable)
