主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)

光在散射介质中的传播，输入光子步数和吸收系数，输出光子的轨迹(A 3-D Monte Carlo Simulation of a photon propagating in scattering and absorbing media. Given an input of the number of steps (iterations) for the photon to take and the absorption coefficient of media, this function calculates a random walk and returns coordinates of final position and total final distance origin.)

A suitable algorithm suggested with wavelet compression for gray scale images based on one- and two-dimension combined hierarchical structure, in the sub-band which has been generated by the aid of several types of wavelet functions. It is shown that the using of combined based hierarchical structures allows us to reduce the calculations complexity of compression and decompression at constant values of compression coefficients
