利用matlab编写的 88行拓扑优化代码(topology optimization)

用此方法拟合椭圆，方法简单，运算量较小，很适合计算机变成实现。(fast ellipse fitting)

利用matlab实现了fft和ifft算法，并给出了利用fft算法解决微分方程的问题的方法。(Fft using matlab achieved and ifft algorithms, and is given the use of fft algorithm to solve the differential equation problem.)

基于matlab gui的电路仿真系统，包括电阻电路仿真、动态电路仿真和时域仿真(Matlab gui-based circuit emulation systems, including the resistance of circuit simulation, dynamic circuit simulation and time domain simulation)

一个神经网络，对100个分布在单位圆上的数据点进行分类。(A neural network, 100 distributed on the unit circle data points classification.)

利用matlab求一段语音信号的时域能量以及频域能量(Demand a voice signal using matlab in time domain and frequency domain energy energy)

说明：  canny算法的一个简易实现,关于两个阈值的连接问题采用了膨胀的方法,较为使用,经比较发现与matlab自带函数相差不大(canny algorithm is a simple implementation, two thresholds on the issue by the expansion of the connection method, the more use, by the comparison function that comes with little difference matlab)

说明：  李亚普诺夫指数指数以及维数的两种算法，比较，及其举例应用(Lyapunov index and dimension index of the two algorithms, comparison, and example applications)
