DateConvert
DateConvert：简单而快速的日期转换
DateConvert转换DATESTR（0）格式的日期向量或序列号和日期向后。
Matlab的DATENUM，DATEVEC和DATESTR接受各种不同意见，但结果他们是缓慢的。如果输入格式正是众所周知，转换可以更快：
DATENUM（ 17 - 10 - 2009 11时08分23秒 ）：2.97秒
DateConvert（ 17 - 10 - 2009 11时08分23秒 ， 号码 ）：0.039秒
=>“1.3％（1000环，1.5GHz的奔腾- M的，利用Matlab 7.7）
DateConvert不*不*验证作为Matlab的日期函数输入日期：
DATEVEC（ 32 - 2 - 2008 25:62:63 ）的答复[2008 3 4 2 2 7]
DateConvert（ 32 - 2 - 2008 25:61:67 ， 载体 ）的答复[2008 2 32 25 61 67]！
因此DateConvert几乎微不足道，但对速度进行了优化。我需要时间排序200 000邮票，并从217个减少到11秒的时间。
请运行单元测试TestDateVec检查的有效性和速度。
测试：利用Matlab 6.5，7.7，7.8，winxp的，32位。
纯Matlab代码，所以兼容性的MacOS，Linux操作系统，64位预期。
英语月份名称是必要的。(DateConvert: Simple but fast date conversion
DateConvert converts the DATESTR(0) format to a date vector or serial date number and backwards.
Matlab s DATENUM, DATEVEC and DATESTR accept a variety of inputs, but in consequence they are slow. If the input format is exactly known, the conversion can be much faster:
DATENUM( 17-Oct-2009 11:08:23 ): 2.97 sec
DateConvert( 17-Oct-2009 11:08:23 , number ): 0.039 sec
=> 1.3 (1000 loops, 1.5GHz Pentium-M, Matlab 7.7)
DateConvert does*not* validate the input date as Matlab s date functions:
DATEVEC( 32-Feb-2008 25:62:63 ) replies [2008 3 4 2 2 7],
DateConvert( 32-Feb-2008 25:61:67 , vector ) replies [2008 2 32 25 61 67] !
So DateConvert is nearly trivial, but optimized for speed. I needed it for sorting 200 000 time stamps and reduced the time from 217 to 11 sec.
Please run the unit-test TestDateVec to check validity and speed.
Tested: Matlab 6.5, 7.7, 7.8, WinXP, 32bit.

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.
