matlab simulink的入门学习资料，挺不错的(matlab simulink introductory learning materials,which is very good)

主要介绍了等精度频率测量原理，该原理具有在整个测试频段内保持高精度频率 测量的优点 同时在该原理基础上，采用了Verilog HDL语言设计了高速的等精度测频 模块，并且利用EDA开发平台QUARTUS11 3 .0对CPLD芯片进行写人，实现了计数等 主要逻辑功能 还使用C语言设计了该等精度频率计的主控程序以提高测量精度。本设 计实现了对频率变化范围较大的信号进行频率测量，能够满足高速度、高精度的测频要 求。-Introduced, such as the accuracy of frequency measurement principle, the principle has in the entire test frequency to maintain the advantages of high precision frequency measurement at the same time the basis of the principle of using the Verilog HDL language, such as the design of a high-speed precision frequency measurement module, and use of EDA Development platform QUARTUS11 3 .0 on CPLD chip to write, and achieved a count of the main logic function, such as the use of C language is also designed such precision the frequency of control procedures to enhance measurement accuracy. This design achieved a wide range of frequency changes in signal frequency measurement, to meet the high-speed, high precision frequency measurement requirements.

给于互相关的鲁棒的多通道的多声源DOA估计(multichannel source DOA estimation)

平台基于visual studio 2015，使用opencv实现霍夫变换检测直线(Implementing Hough Transform)

说明：  //以上的代码加载了两个PCD文件得到共享指针， //后续配准是完成对源点云到目标点云的参考坐标系的变换矩阵的估计， //得到第二组点云变换到第一组点云坐标系下的变换矩阵 // 将输入的扫描点云数据过滤到原始尺寸的10%以提高匹配的速度， //只对源点云进行滤波，减少其数据量，而目标点云不需要滤波处理 //因为在NDT算法中在目标点云 对应的 体素网格数据结构的 统计计算不使用单个点， //而是使用包含在每个体素单元格中的点的统计数据(The following links describe a set of basic PCL tutorials.

csv文件读取和存储，可用于显示在QT建的表格中(csv file is read and stored, can be used to display the built form QT)

本程序用于测试实时时钟模块SD2000的SRAM存储器D/E系列， 程序功能如下： 1. 关闭/INT1及/INT2的中断输出 2. 初始化时间(写时间数据) 3. 在BREAKPOINT1设断点时,依次读时间-写SRAM数据-读SRAM数据循环 4. 全速执行时,LED四位分别显示小时和分钟的值-procedures used to test the real-time clock module SD2000 SRAM memory D/E Series, procedures following functions : 1. Closed/INT1 and/INT2 the interruption of output 2. Initialization time (the time to write data) 3. Located in BREAKPOINT1 breakpoint, followed by time for-write SRAM data-reading cycle of four data SRAM. full speed of implementation, respectively, four LED display hours and minutes values
