对偏微分方程进行差分计算

切比雪夫滤波器，可以很好的实现滤波功能。(Chebyshev filter, can achieve very good filtering.)

该文件中包含有常微分方程初值问题的四种数值解法，分别是：RK4法，AB4法，AB4_AM4预测矫正法和改进的AB4_AM4法(The document contains the initial value problem of ordinary differential equations of the four numerical method, namely: RK4 method, AB4 Act, AB4_AM4 forecast correction method and improved method AB4_AM4)

这是个卡尔曼滤波的递推程序，是用MATLAB实现的，很有用出的，希望对大家有所帮助(This is a recursive procedure of Calman filter is implemented in MATLAB, a useful, and they hope to help everyone)

This code is NUMBER1: MATLAB code for paper: calculation of electron energies in a quantum well using the transfer matrix method. we solve the time independent schrodinger equation in 1D AlGaAs/GaAs/AlGaAs quantum well using the transfer matrix method. We define a wave function for each point of well and barriers and convert it to a 2in2 matrix. Multiplying of matrixes with boundary conditions results in discrete energies and their wave functions. We compare our results with other simulations and calculate discrete energies for different wells.
