本实验将使用MATLAB 7.0软件分别对20钢的离子渗碳和气体渗碳过程进行模拟，渗碳时间分别为1h、2h、8h、20h，渗碳温度分别为1203K、1223K、1273K、1323K。对20钢的其中一面进行一维气体渗碳，设该扩散系数和界面传递系数均与渗碳浓度无关，对渗碳厚度、渗碳速度、渗碳量和渗碳时间、渗碳温度的关系进行模拟。(In this study, using MATLAB 7.0 software 20 steel ion carburizing and gas carburizing process simulation, carburizing time were 1H, 2H, 8h, 20h, carburizing temperature of 1203K, 1223K, 1273K, 1323K. 20 steel one side of a one-dimensional gas carburizing, set the diffusion coefficient and interface transfer coefficient has nothing to do with the concentration of carburizing, the relationship of the thickness of the carburizing, carburizing speed, carburizing and carburizing time, carburizing temperature simulation.)

基于 MATLAB 的语音信号分析与处理的课程设计.录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法或双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的语音信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号(MATLAB-based voice signal analysis and processing of the curriculum. Record a voice signal itself, and the recorded signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum filter performance given by using window method or the bilinear transformation to design a filter, and draw the filter frequency response then filter of their own design collection of the speech signal is filtered, the filtered signal to draw the time domain waveform and frequency spectrum, and filter the signal before and after comparison, analysis of signal changes playback voice signal)
