递推最小二乘算法，MATLAB程序，系统辨识(Recursive least squares algorithm, MATLAB program)

说明：  图像色彩空间RGB到HSL的转换Matlab程序。(images to RGB color space conversion Matlab HSL procedures.)

陀螺加表数据发生器，可以自动生成足够数量的数据。(Gyro Add table data generator can automatically generate a sufficient number of data.)

本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

说明：  实现了用rs232接口传入数字信号，并且可通过键盘输入对模数转换器放大率的数值改变(Achieved with a rs232 interface, the incoming digital signal, and keyboard input to the ADC through the magnification of the numerical change)

LCMV波束形成，线性约束最小方差，两个信号，一个期望信号，一个干扰信号。(LCMV beamformer, LCMV, two signals, a desired signal, an interference signal.)

基于matlab的二维低通滤波器的设计，可用于图像滤波(Matlab-based two-dimensional low-pass filter design can be used for image filtering)
