用LAPLACE方法求解多维沃尔泰拉方程，此处为一个变元的方程，由于该方程同时含有微分和积分，一般求解有一定的困难。此处为MATLAB程序，注意不同的边界条件(used method for multiple preoperational Ertaila equation here as a variable element of the equation, As the same time contain differential equations and integral, the general solution is definitely difficult. MATLAB here for the procedures, attention to the different boundary conditions)

分形曲面的matlab简单程序，已经测试过。(Fractal surface matlab simple procedure, has been tested.)

This program code is for compressing a file or image using Huffman coding without any built-in functions.

DC motor is a device that converts electrical energy into mechanical energy. DC motor structure consists of two main parts: a permanent magnet and a coil. There is also a brush which is connected to an external electric power to the coils of the motor. When coil is powered on, there is a magnetic field around the coil.
