说明：  《MATLAB 7.0编程基础》第6章 （源码实例）主要讲解MATLAB图形基础("MATLAB 7.0 programming foundation" Chapter 6 (source code examples) mainly based on MATLAB graphics)

This is jpeg compression code for images

仿真了锁相环工作到一定时间后达到锁定状态的过程，程序采用的是一阶RC低通滤波器即二阶一型环(Simulation of the PLL to work until after a certain period of time to achieve lock-state process, the procedure is used first-order RC low-pass filter that is second-order one-ring)

说明：  对输入的信号计算其的分形维数，用以判断信号的复杂度(The input signal to calculate the fractal dimension of complexity to determine the signal)

这是求导波中lamb波频散方程很好的MATLAB代码 绝对好用(To solve the dispersion curve of lamb wave by use of MATLAB program)

分析正弦稳态电路，建立网孔电流方程求解电路电流，采用GUI直观形象的显示电流向量图(Sinusoidal steady state circuit analysis, mesh current equations to establish the circuit current, using an intuitive GUI displays the current image of the vector map)
