一个相当好用的matlab函数，由美国国家可再生能源实验室科研人员设计，可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations. The authors of the original paper state that this algorithm should be precise at+/- 0.0003 degrees. I have compared it to NOAA solar table (http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good correspondance (up to the precision of those tables), except for large zenith angle, where the refraction by the atmosphere is significant (difference of about 1 degree). Note that in this code the correction for refraction in the atmosphere as been implemented for a temperature of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction un_topocentric_zenith_angle_calculation� for a possible modification to explicitely model the effect of temperature and pressure as describe in Reda & Andreas (2003). )

基于MFCC参数和DTW算法的语音识别算法，对0-9这十个数字的中文发音进行识别。该程序对特定的三个人的声音做训练，并用来识别这三个人之外的30个人的发音，即特定人的集合外的识别，程序中已有语料。(The MFCC parameter and DTW algorithm-based speech recognition algorithm, the 0-9 ten digits Chinese pronunciation recognition. Do training of the program on the specific person' s voice and is used to identify these three individuals outside of the 30 individual pronunciation, i.e. the identification of the collection of a specific person, the program already corpus.)
