说明：  c语言编写的高效用LU分解法求任意维数的矩阵的逆，它是经典书籍《算法导论》（第二版）中矩阵求逆的c语言实现。 (The algorithm of matrix inverse is based on LU decomposition which is proposed by the book of introduction to algorithm (second edition).)

说明：  本程序计算的太阳角有地面点对应的太阳天顶角和太阳方位角，太阳高度角与太阳天顶角 互余，所以太阳高度角也可以通过90 度-太阳天顶角计算得到(The solar angle is calculated by the solar zenith angle and the sun azimuth angle corresponding to the earth's surface point. The sun height angle and the sun zenith angle are complementary, so the sun height angle can also be calculated by the 90 degree sun zenith angle.)
