Abstract The study of digital signal processing normally concentrates on the design, realization, and application of single-input, single-output digital filters. There are applications, as in the case of spectrum analyzer, where it is desired to separate a signal into a set of sub-band signals occupying, usually nonoverlapping, portions of the original frequency band. In other applications, it may be desired to combine many such sub-band

异步电机矢量控制仿真模型，采用间接磁场定向控制策略，电机模型没有采用matlab自带电机，而是根据两相旋转坐标系下的电机方程自己搭建了一个电机模型。(Induction motor vector control simulation model, using the indirect field oriented control strategy, the motor model comes with no motor using matlab, but according to the two-phase rotating coordinate system of the motor equations built himself a motor model.)

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.
