2d photonic band structure calculation program

本程序主要是用于求解目标函数的凸优化问题。(This procedure is mainly used to solve the objective function of the convex optimization problem.)

主要讲解了matlab在数学建模中的基础运用,对初学者较有意义。(the use of matlab in the CMCM.)

说明：  利用matlab实现了多个无人机协同飞行编队(Using MATLAB to realize UAV flight formation)

hetman problem and c source code

quadotor simulation using Matlab with several subsroutine, PID controller is described and applied to non linear model of quadrotor UAV

用于结构在动力荷载作用下的时程分析,地震荷载，随即荷载均可，采用newmark方法(For structural time history analysis under dynamic loads, seismic loading, then the load can be, using the newmark method)

使用c语言及c++来实现matlab编程(using c or c++ to complete matlab programing)

龙格4阶matlab仿真 进行数据仿真运算看可以进行调用和修改(runge MATLAB m-file)

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). )
