说明：  语音识别中，提取MFCC特征参数时用到的MEL滤波器组函数，函数名为melfb(the function of melfb for speech recognition)

其中有很多matalab程序的例子，很适合学习matalab编程。有一定的参考价值(There are many examples of matalab program, very suitable for learning matalab programming. Have certain reference value )

高斯滤波程序，非常好用，在重力计算和频域内计算中都可以使用(THE GAUSSION FILTER PROGRAMS)

说明：  完成TDOA的chang和fang算法，画出了对应的算法散点图及位置误差图像(The simulation of TDOA chang and fang.)

基于BP神经网络的PID控制算法，可以实现对正弦、方波、阶跃信号的跟踪(BP neural network based on the PID control algorithm can be achieved for the sine, square, step tracking signal)

使用MATLAB实现对信号的fft变换从而进行频谱分析(The use of MATLAB to achieve transformation of the signal in order to carry out the fft spectrum analysis)
