Mean-scales data table Z (new operation or based on know parameters), or reverses mean-centering operation.

matlab gui程序，进行控制系统典型环节的演示，包括典型环节运行效果的演示与代码的展示。(a matlab gui program, it displays the typical segment of control system)

相位解缠是INSAR数据处理的重要步骤，本文用基于FFT的最小二乘法实现实现相位解缠(Phase unwrapping)

实现功能 1) 在用户界面设置录音时长并实时录音 2) 调节放音幅度、播放原声并进行时域、频域绘图 3) 对收集的声音进行倒放处理并播放 4) 对收集声音进行回声处理并播放，比对时域波形 5) 对收集声音进行回响处理并播放，比对时域波形 6) 对经过回声处理的声音进行回音消除并比对时域波形 7) 采用自适应滤波器消除采集声音中的环境噪音 8) 设计相应的滤波器组成均衡器对收集的声音进行处理并播放 9) 男女声识别 10) 设计参数可调的滤波器对采集的声音进行处理 (1) in the user interface to set the recording length and real-time recording 2) to adjust sound, played acoustic amplitude and time domain, frequency domain mapping 3) to upend the collection of sound and play 4) to collect sound echo processing and playback, than in the time domain waveform 5) to collect sound echoes, processing and playback, than in the time domain waveform 6) to echo and treated with echo s voice than in the time domain waveform 7) using adaptive filter to eliminate ambient noise in acquisition voice 8) to design the corresponding filter to process the voice of equalizer to collect and display 9) NanNvSheng recognition 10) tunable filter design parameters for voice processing )

APF，即有源电力滤波器的仿真模型，自己搭建的，仅供参考。(APF, namely active power filter simulation model to build their own reference purposes only.)

说明：  卫星导航与定位中的easy程序：将原始观测数据O-files转换到GPS时间（week+sow）；利用原始观测数据N-files中的时间和星历表计算位置的地心地固坐标；从O-files和N-files获得数据，仅使用伪距，对大于20组的数据进行重复计算，并利用迭代最小二乘法，计算接收机地心地固位置等功能。(Easy program in satellite navigation and positioning: convert the original observation data o-files to GPS time (week + sow); use the time in the original observation data n-files and ephemeris to calculate the geocentric and geocentric coordinates of the location; get the data from o-files and n-files, only use pseudo distance, repeat the calculation of more than 20 groups of data, and use iterative least square method to calculate the receiver geocentric and geocentric Fixed position and other functions.)

《MatLab工程数学应用》是很多研究生做工程时必备的一本参考书。很好用。(" MatLab Engineering Mathematics Applications" is a lot of graduate students to do projects must have a reference book. It just works.)

This function creates text objects that mimic x and y tick labels, while the original tick labels are removed. The text object format allows more modification (such as color, rotation, etc) than the original tick labels, and also allows TeX strings to be utilized in tick labels (see xformat and yformat inputs for more details).
