此程序实现了一种改进的ofdm下的信道估计方法，综合了以往的几种内插方法，并加以改进(This program realise a new channel estimation beneath the ofdm system combining several former intersecting method.Furthermore, certain ameliorations are also being done.)

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.
