说明：  如何将Excel中的数据转入到matlab中(how to translate the data in excel into matlab)

三维图像输出，针对于变成过程中遇到的三维三点图像输出等问题得到了解决(Three-dimensional scatter plot phase output)

解模块线性方程组, solve modular linear equations, 用到了extended-euclid算法求最大公约数...(solve modular linear equations, use extended-euclid to compute the greatest common divisor..)

一个求解纳什交换的均衡问题的例程，运用了类似基因表示的做法，需要的请自行下载(Nash for a balanced exchange of the routines that use a similar approach expressed by the gene, Requests need to download)

这是有关正弦波频率估计的几种算法，包括过零点检测，rife算法，music算法，levensen法，周期图法等7种不同算法。(This is several algorithm for frequency estimation of sinusoid, including zero crossing detection, rife algorithm, music algorithm, levensen method, periodogram method 7 different algorithms.)

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，采用窗函数法和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；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)

离散点拟合贝塞尔曲线，可以改变阶数，求控制点并求出误差(Fitting Bezier curve with discrete points)

说明：  多元微分方程参数识别，对网友的问题进行编程，并求出了准确结果，使用最小二乘lsqcurvefit函数 (multiple variable differentical equtation parameter estimation using matlab lsqcurvefit function,the reslut is good)((multiple variable differentical equtation parameter estimation using matlab lsqcurvefit function,the reslut is good))

source code in Matlab, function for image thinning, using 2 different algorithm for image thinning. So you can compare that.
