经典的隐写算法，包括LSB替换和随机LSB匹配。对于实现简单的信息隐藏最常用的方法，具体用matlab实现。(This is LSB steganography, it includes LSB replacement and random LSB matching. it is most common method for information hiding, and it implement with matlab)

matlab应用，一个小波变换的滤波实例应用。(matlab application, a wavelet transform filter example application.)

该程序是基于matlab的LMS自适应滤波器程序（matlab)(LMS program (matlab))

计算圆波导模式（例如TE21、TM11，可以输入不同的m、n值）的场分布。(Calculate the circular waveguide mode (eg TE21, TM11, you can enter a different m, n value) field distribution.)

Fixed lag smoother, some errors are modified.

正弦信号叠加高斯白噪声，通过IIR低通滤波器，并画出时域和频域上的波形频谱图(Sinusoidal signal superimposed Gaussian white noise through the IIR low-pass filter, and draw on the time domain and frequency domain waveform spectrum)

关于小波分析的matlab程序，大家可以参考一下~(On wavelet analysis matlab program, we can refer to)

matlab 技术期刊，对于学习matlab很实用(Matlab technical journals, it is very useful for learning matlab )

NOTE: This function modifies the BUTTONDOWNFCN of axes in the input list, and their children. However, it will not modify any object whose buttondownfcn is nonempty.
