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)

说明：  本程序经过本人的调试运行，能够实现对手写数字的识别，成功率达 80(After I debug this program to run, to realize the handwritten digit recognition, the success rate of 80)

实现eemd程序，可以进行内禀模态函数的分解。(eemd)

对lena图进行混沌置乱，简单方便。初值选定x=0.5,u=3.7。(Lena diagram of the chaotic scrambling, easy and convenient. Initial value of the selected x = 0.5, u = 3.7.)

有源滤波器的matlab仿真程序，使用了ip-iq电流检测法，中间使用滞环控制产生了控制脉冲，进而实现了谐波电流的补偿，和大家分享了(Active Filter matlab simulation program, using the ip-iq current detection method using hysteresis control generates intermediate control pulse, thus achieving a compensation of harmonic currents, and share the)
