说明：  在matlab下，运用矩量法计算圆环形细导线电容及电荷分布，并分析电容随导线半径和圆环半径的变化(In matlab, compution of the annular thin wire capacitance and charge distributionwith MOM, and analysis of capacitor with the conductor radius and the radius of the circle)

偏微分方程的MATLAB解法 陆君安编著 PDF，讲的是matlab的pde工具箱(MATLAB Solution of Partial Differential Equations Jun-An Lu edited PDF, talking about the matlab pde toolbox)

详细画出了时域和频域的相关图，包括面积、周长、矩形度、伸长度，采用的是脉冲对消法。( Correlation diagram shown in detail the time domain and frequency domain, Including the area, perimeter, rectangular, elongation, It uses a pulse of consumer law.)

this is the code to apply hilbert transform on a signal.

说明：  自动控制原理中的波的图的画法以及相关的程序语言(bode matlab)

4psk信号的蒙特卡洛误码率仿真，与理论误码率的对比(Monte Carlo signal 4psk BER simulation, and theoretical bit error rate comparison)

这是一个实现拉格朗日插值的数学程序，也很经典。(This is a mathematical realization of Lagrange interpolation process is also very classic.)

说明：  盲估计随机序列gamma校正，去除序列的非线性(Blind Estimation of random sequence gamma correction, removal of non-linear sequences)
