matlab下的两步法标定程序，应该对大家有所帮助(matlab under the two-step calibration process should be helpful to everyone)

This is the machine-generated representation of a Handle Graphics object and its children. Note that handle values may change when these objects are re-created. This may cause problems with any callbacks written to depend on the value of the handle at the time the object was saved. This problem is solved by saving the output as a FIG-file.

ldpc码校验矩阵的生成函数，测试可以使用的文件啦啦(Lala code file generation function ldpc parity check matrix, the test may be used)

采用多模方式的卡尔曼滤波程序，仿真对运动目标的跟踪(Using multi-mode approach of Kalman filtering process, simulation of moving target tracking)

Matlab小问题 问: Matlab仿真中怎样编辑Scope中的图象??? 答: 实现的方法有以下的几种: 1）PrintScreen，然后粘贴到Windows位图编辑器，选择图像点击右键，选择“反色”即可； 2）在Scope中，它的参数设置的第二页，有一个Save Data to Workplace，将它选中，然后在下面的方框 中指定变量名，然后用plot命令画出； 3）直接在模型上再加一个，to Workplace模块，也用plot画出； 4) 等scope显示出来图像以后，在matlab上运行 set(0, ShowHiddenHandles , On ) set(gcf, menubar , figure ) 这时候你会发现scope的工具栏的上面多了一行，点击insert-axes，鼠标会变成十字形状，然后再图像的任意一处双击左键出现一个对话框PropertyEditor，选中style在窗口的右便会出现color，这时你就可以任意修改背景颜色了。 问: 怎样进行S-function的编程和使用??? 答: S-function也就是System-function的缩写。说得简单，S-function就是用MATLAB所提供的模型不能完全满足用户，而提供给用户自己编写程序来满足自己要求模型的接口。要了(err)

说明：  求两个方波信号的卷积，对两个方波信号进行卷积计算，通过比较输入的两个信号和输出地卷机信号来说明卷积。(Demand convolution of two square wave signals, the convolution of two square wave signals calculated by comparing two input signals and output signals to paper machine to illustrate convolution.)

用R/S估算法计算时间序列的HURST指数(With R/S method to estimate time series HURST index)

说明：  L1_PCA降维,L1_ARPCA降维等算法介绍以及实现，可以直接跑，如有侵权，麻烦告知，谢谢(L1_PCA dimensionality reduction,L1_ARPCA dimensionality reduction algorithm introduction and implementation, can run directly, if there is infringement, please inform, thank you)

本语音频谱分析程序对三个重要的谱（即短时谱、倒谱和LPC谱）分别做了仿真分析，这样为以后进一步研究语音打下了基础。(The voice spectrum analysis program three important spectrum (ie short-term spectrum, cepstrum and LPC spectrum) is simulated separately, so that voice for the future foundation for further study.)
