matlab资料汇总，内含有基本使用手册以及详细的进阶过程，适合初学者以及放在手边随时使用(matlab data collected, as well as a detailed manual contains basic advanced course is suitable for beginners as well as at hand ready for use)

matlab 编写的画图程序，用来画电阻率曲线的代码。(matlab prepared Paint program, used to draw resistivity curve code.)

计算Fisher的函数，根据Fisher可以计算出克罗美下界(Fisher s exact test is a statistical test used to determine if there are nonrandom associations between two categorical variables[1]. The job of Fisher s exact test with 2 x 2 or 2x 3 contingency table is already easily done by others. However, the one with n x m contingency table hasn t found , or with bad computation. This function efficiently deals with Fisher s exact test with n x m contingency table. As for the function :)
