PIDMATLAB

说明：  给图像添加噪声，驱除噪声，具体的说就是先添加高斯噪声等等，然后通过中值滤波，自适应滤波等等(Add noise to the image, get rid of noise。Specifically, it is the first toadd Gaussian noise, etc., and then median filtering, adaptive filtering, etc. )

bpsk的解调源代码，可以用于仿真，理解解调过程(bpsk demodulation source code can be used to simulate and understand the demodulation process )

传统的pid控制算法,系统函数是无时滞的,采用增量式的pid控制算法.(traditional pid control algorithm, the system function is without delay, using the incremental pid control algorithm.)

MATLAB提供了各种曲线拟合方法，例如：Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等，当然，也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数，还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据，非常好用。但是如果我们已经确定了拟合的方法，只需要对数据进行计算，那么这种GUI的操作方式就不太适合了，比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)
