对国际上通用的标准Shepp-logan人头模体进行投影和反投影、滤波反投影、ART和SART重建。(include anisotropic filter, bilateral filter and functions for tomographic reconstruction using BP, FBP, ART, SART, LSQR algorithm)

应用于多峰值MPPT问题，采用PSO寻找最大功率点，具体实现在S-function中，仿真时建议找一个内存大的电脑用连续仿真，离散在这种仿真时容易出问题。自行读程序只需输入光伏电压电流即可实现，仿真多峰值问题时光伏板注意反并联二极管，输出为占空比，boost、隔离boost都可以使用(For multi-peak MPPT problem, PSO is used to find the maximum power point, which is realized in S-function. It is suggested that a computer with large memory be used for continuous simulation. Discrete simulation is prone to problems. The self-reading program can be realized only by inputting photovoltaic voltage and current. In the simulation of multi-peak problem, the photovoltaic board pays attention to the anti-parallel diode.)

这个是基于matlab的维纳滤波设计，其中包括两个列子，一个是在时域实现滤波器，一个是在频域实现滤波器，两个列子都是对chirp信号进行处理的(there are two examples for weina filer desined in matlab ,one is achieved in frequency domain and another is achieved in time domain.the two weina filers are desined to remove noise from chirp.)
