四面体单元

主要是交通行业的时空矩阵的3维热力图表达方式，不同检测器与不同时间段的流量作为颜色的第三位导入，热力图调整颜色表达更清晰(mianly used for transportation engineering. It can plot the three dimension of the real traffic situation, including different temporal and spatial. the code also can modify the parameter of the colorbar.)

数学中的通径分析问题，主要用于数学实验方面，计算数学中的数据分析(Path analysis of mathematical problems in)

计算材料学中用相场法模拟合金凝固相变的程序(Computational Materials Science using phase-field simulation of solidification phase change process)

对加速度数据进行二次积分，最终得到位移数据。(Double integration of acceleration data and the final displacement data.)

由工况HWFET数据和整车参数来计算整车瞬时需求功率，并绘制出功率需求图。(The instantaneous demand power of the whole vehicle is calculated by the HWFET data and the vehicle parameters, and the power demand map is drawn.)

说明：  fluent 二次开发，udf编程参考，c语言编程(Fluent udf coding c language multiphase flow)

说明：  朴素贝叶斯算法，以函数形式实现，花了一个上午的时间(Naive Bayes algorithm, in order to function the form of implementation, a morning flower time)

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

计算任意两个等维矩阵之间对应坐标点的距离(Calculate the distance between the corresponding coordinate points of any two equal dimensional matrices.)

说明：  吉尔数值算法，求解刚性微分方程组，稳定好，收敛好(Gill numerical algorithm, good stability and convergence for solving rigid differential equations)
