求解兰伯特问题，求解二体问题下已知初始位置和终端位置进而得到轨道(solve Lambert problem. people can solve many problem by this matlab lib)

说明：  基于PCA的人脸表情识别，可以辨别高兴，愤怒和厌恶三种表情。 (In this project, Eigenfaces are used to classify facial expression. It has been assumed that, facial expression can be classified into some discreet classes (like anger, happiness, disgust or sadness) whereas: 1. Absence of any expression is the "Neutral" expression 2. Intensity of a particular expression can be identified by the level of its "dissimilarity" from the Neutral expression)
