Lookup a chemical element based on Symbol, name, or atomic number

用matlab编写的欧拉方法求解常微分方程：数值分析中很经典的代码(a procedure of Euler method solve pde )

有限差分正演模拟 波场快照 存为gif动画(finite difference modelling)

this is multilayer perceptron neural network

IIR滤波器的matlab实现，代码精简，实用。(IIR filter matlab realize, code streamlining and practical.)

用MATALB做的曲柄滑块机构的动画（包括加速度、速度和位移的变化分析）代码(Do with MATALB animation slider-crank mechanism (including acceleration, velocity and displacement change analysis) code)

利用频率采样设计法设计线性相位FIR低通滤波器，画出h（n）、幅频响应、相频响应(Design of frequency sampling design method using a linear phase FIR low-pass filter, draw h (n), frequency response, phase frequency response )

一个滤波器的设计，大家看看了！！！！！！！！！！！！！(filter)

The program simulates convolutional code using soft-decoding viterbi algorithm. The choice of generator matrix (G) determines the code rate (1/R) and constraint length of the code (K).

matlab的sift算法调用库，很简洁(The sift algorithm matlab library calls, very simple)
