MATLAB是一种用于科学工程计算的高效率高级语言。MATLAB的基本数据单位是矩阵，它的工具箱已经延伸到了科学研究和工程应用的许多领域。它在诸如一般数值计算、数字信息处理、系统识别、自动控制、振动理论、时序分析与建模、优化设计、神经网络控制、动态仿真系统、金融管理、小波分析、特殊函数和图形领域表现出一般高级语言难以相比的优势，并可以方便地用于几乎所有的科学和工程计算的各方面。(MATLAB is a science and engineering computing for efficient high-level language. MATLAB' s basic data unit is the matrix, and its toolbox has been extended to scientific research and engineering applications in many fields. It is in such general numerical calculation, digital information processing, system identification, automatic control, vibration theory, time series analysis and modeling to optimize design, neural network control, dynamic simulation system, financial management, analysis, special functions and graphics in the field show generally difficult to match the advantages of high-level language, and can be easily used in almost all scientific and engineering computing aspects.)

用两点法辨识一阶惯性滞后系统，测试结果比例系数和时间常数辨识结果较准确，但输入延迟时间差距较大，分析其原因，可能是因为在曲线上取的两点坐标不准确，因为离散的数字量坐标取值方法有误。(Two points )

通过matlab编程对齿轮传动的参数进行计算，得出各项啮合尺寸。(Matlab programming through the parameters of the gear calculations, the meshing size.)

图像频域滤波，用matlab实现了在图像频域中通过Butterworth陷波器消除周期性噪声干扰信号。(Image frequency domain filtering using matlab achieved in the frequency domain image by Butterworth notch filter to eliminate periodic noise signal.)

this is a code for square detect in image using transform

Robust PCA and subspace tracking

FFT for ground motion
