SVD-DCT_Image_watermarking

射频电路设计，微波设计中常常用到的smith原图，本程序利用MATLAB编程画出smith原图，可以帮助射频电路设计，比如画等功率匹配圆，等阻抗圆，等反射系数圆等。(RF circuit design, microwave design is often used smith artwork, this program using MATLAB to draw smith original programming that can help RF circuit design, such as painting and other power matching round, such as impedance circle, so the reflection coefficient circle and so on.)

这是一个在matlab环境下的字符统计函数。形参是你需要统计的文件在matlab路径下的地址。(This file is aimed at calculates how many characters in direc s file.You should first set the direc of your file,then f=chsta(direc) and everything is ok.)

this function is used for linear fitting data
