MATLAB无约束一维极值问题，解决无约束的一维极值问题(very good)

用Matlab实现四种混沌调频信号并画出其功率谱图(make four chaotic frequency modulation signal and its power spectrum plotted on a graph)

我这儿有一组若干年份的数据，是按一定时间顺序排的，想用曲线拟合法得到2010年的人均国内生产总值，不知怎么用matlab，高手赐教！！！！！！可加分 年份 人均国内生产总值(元) 1996 27000 1997 30619 1998 33282 1999 33689 2000 41020 2001 43344 2002 46030 2003 53887 2004 59271 2005 64507 2006 70597 07.1季 20505 07.2季 19619 07.3季 19874 07.4季 19223 08.1季 19703(I have a group here, a number of years of data are ranked by order of a certain period of time, and want to use curve fitting to be in 2010 the per capita gross domestic product, I do not know how to use matlab, you let us know! ! ! ! ! ! Add points to the year the per capita GDP (Yuan) 1996 27000 1997 30619 1998 33282 1999 33689 2000 41020 2001 43344 2002 46030 2003 53887 2004 59271 2005 64507 2006 70597 07.1 quarter 19,619 07.3 quarter 20,505 07.2 quarter 19,223 08.1 quarter 19,874 07.4 quarter 19,703)

详细介绍了在MATLAB环境中，MAT文件的编辑与读写，通常使用load和save两个命令进行 MAT 文件的读和写(Described in detail in the MATLAB environment, MAT files editing and read and write, load and save commonly used two commands to read and write MAT files)

matlab教程和例程，matlab时频分析一书中的工具箱，有两个这是其一。(matlab tutorial and routine, matlab frequency analysis book toolbox, two is one.)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

求脉率的小demo，有任何问题可以联系我。(A demo about the value of pulse rate .If there any questions ， you can contact me.)
