Description: This submission contains a function that computes face normal data for the VertexNormals property of the surface that fixes the lighting (facenorm.m) as well as a workaround function that you can just use in place of surf (surfo.m).
Only use this if you get erroneous surface plots and you can t go without OpenGL and flat lighting.-This submission contains a function that computes face normal data for the VertexNormals property of the surface that fixes the lighting (facenorm.m) as well as a workaround function that you can just use in place of surf (surfo.m).

Description: InPolyedron detects points inside a manifold closed surface (even non convex ones). The normal orientation is assumed to be outwards. Warning there is no check for closed surface or normal orientation, open surfaces will give nonsense results.
In the limit of numerical accuracy, points lying on the surface will be considered in.
Usage
Input:
■p: points of the surface npx3 array
■t: triangles indexes, first points flagged as one, ntx3 array
■tnorm: outward normals of traingles, ntx3 array
■qp: points to be queried, nqx3 array
Output:
■in: nqx1 logical vector, true for in, false for out-InPolyedron detects points inside a manifold closed surface (even non convex ones). The normal orientation is assumed to be outwards. Warning there is no check for closed surface or normal orientation, open surfaces will give nonsense results.

Description: 吉布斯定轨法。
输入：轨道上任意三个点的位矢(R1,R2,R3)；
输出：质点在R2端点时的速度V2；ierr是个判断符号，返回的ierr是零的话，就说明‘R1,R2,R3’共面，如果ierr是1的话说明‘R1,R2,R3’不共面(正常情 况下，要构成轨道的话，‘R1,R2,R3’一定共面 ，即ierr是零，如果ierr是1的话说明输入的‘R1,R2,R3’不共面不能构成轨道。
此函数用于：任意给定三个空间共面的向量，可以确定质点在R2处的速度V2，也就得到了轨道上的一个状态向量(R2,V2),调用前面的函数就可以确定其轨道，及任意时刻的状态。-Gibbs set the track method. Input: track any three points of the bit vector (R1, R2, R3) output: particle at R2 endpoint speed V2, ierr is a judgment symbol, The ierr that is returned is zero, then, it means' of R1, R2,, R3, ' coplanar, if ierr is 1, then description' of R1, R2,, R3, ' not a total surface (under normal circumstances, you want to constitute a track, then,' of R1, R2, R3, ' a certain total surface, ierr is zero, if ierr is an instructions to enter the words ' of R1, R2, R3' coplanarity can not constitute a track. This function is used: for any given three space vector of the surface, can determine the particle at the speed V2, R2 also track a state vector (R2, V2), call the previous function can determine its orbit, and at any time of the state.

发：1000、5000、10000、20000、30000个粒子。
利用2维数组记录每个点的粒子数。
初始粒的横纵坐标为0～40的均匀分布。
能量为（15，3）的正态分布。
在基体表面自由行走时损失1的能量。
若该点有粒子，即与其他粒子相遇时损失3的能量。
由低处向高处扩散，每扩散一层，损失4的能量，由高处
向低处扩散，损失3的能量。
当粒子的能量小于等于0时停留下来，该点的粒子数加1。
临界核的尺寸为10个粒子。
根据每个点粒子个数的不同，以不同的灰度显示这些点。
点越亮，则表示该点的膜越厚。
