you can use this matlab code to change image into different color system such as luv, rgb, yuv and lab

多變數目標函數最佳化,可自行設定變數上下界範圍(optimization of the objective function for several variables)

matlab计算器 简单加法，初学者很好的入门源码，功能简单，很精巧……(it s a simple matlab program.)

薛定宇教授的ctrllab 好东西！直接运行ctrllab 即可 (Mr.Xue s ctrllab!run ctrllab directly !)

巴特沃斯滤波器，主要实现的是低通信号，此功能模块的低通曲线很符合理想的幅频特性。(Butterworth filter, the main achievement is low traffic numbers, the low-pass curve is consistent with this function module ideal frequency characteristics.)

说明：  G.729编码，解码的程序实现。支持多种语音格式。(G.729 encoding and decoding process realization. Support multiple audio format.)

FDTD方法是把 Maxwell 方程式在时间和空间领域上进行差分化。利用蛙跳式(Leap frog algorithm)--空间领域内的电场和磁场进行交替计算，通过时间领域上更新来模仿电磁场的变化，达到数值计算的目的(FDTD method Maxwell s equations in the field of time and space differencing. Leapfrog (of Leap frog algorithm)- the electric and magnetic fields within the field of space alternating the update time field to mimic the changes in the electromagnetic field to reach the numerical calculation purposes)
