非线性方程计算各种方法的matlab程序，可作为数值分析等的学习工具。(Nonlinear equations to calculate the various methods matlab program, can be used as a learning tool of numerical analysis .)

k近邻算法和KALMAN滤波相结合的一个实例论文(k nearest neighbor algorithm and the KALMAN filter paper an example of combining)

实验结果表明该算法对非冲击噪声效果良好。 lx_main为主程序，NS_lxwz为噪声估计模块，lxG_wz为增益估计模块，noise_sound为测试用含噪语音。 算法原理参见本人的文章《一种引入延迟的语音增强算法》。(Experimental results show that the algorithm for non-impulsive noise effect is good. lx_main the main program, NS_lxwz for the noise estimation module, lxG_wz for the gain estimation module, noise_sound to test the noisy speech. Algorithm theory see my article " delay the introduction of a speech enhancement algorithm." )
