Jacobi
Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。
若其特征值全为正,则此Jacobi矩阵正定,即它的任何二次型都大于零。并且如果是对称Jacobi矩阵,还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根
det(A-xI)=0(Jacobi)

sun_position
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). )
