说明：  用Fortran编程求解简单的一元二次方程案例(Solving quadratic equation of one variable)

contourlet变换工具箱，附带贝叶斯阈值去噪(Toolbox contourlet transform, with Bayesian threshold denoising)

ivf Fortran 有限元计算 一端固支 另一端自由移动的二维梁结构的振动(calculate the 2D beam vibration based on Finite Element Method in Fortran)

说明：  基于python的多项式曲线拟合，本程序以1 3 5 9次为例子。(Based on the polynomial curve fitting of python, this program takes 1 3 5 9 times as an example.)

改程序是计算出金属表面等离子体直波导的有效折射率随波长和传输长度随波的两色散曲线，另外给定Drude-Lorentzia模型参数给定后，还可以求解介电常数以及画出相应实部和虚部的曲线(This programer is used to calculate Ag relative dielectric constant accroding to the Drude-Lorentzia and sovle the transcendental equation for even illumination. At the same time,it can draw the diagram of relationship between the dispersion curve and the Transmission with the length. )

同时正交匹配追踪算法的MATLAB程序，一些文献中也被翻译成同步正交匹配追踪。(Simultaneous Orthogonal Matching Pursuit(SOMP))
