维纳滤波,可以有效的对信号进行白噪声的滤除(weina filter)

运用MATLAB语言，对于给定的图片，做DFT,DCT等各种变换，并进行压缩(The use of MATLAB language, for a given picture, do DFT, DCT and other transforms, and compression)

本程序实现2006年由Morelli提出的lear all(This program realization of 2006 by the proposed Morelli Lear all)

The function takes at least three input arguments (function, its derivative, and an initial guess). After iterations, it gives the root of the function. The fourth input argument is to change the stopping criteria.

Matlab编程（Stephen.J.Chapman编.刑树军.郑碧波译.），适用于初学者快速入门。(Matlab programming, suitable for beginners to get started quickly.)

说明：  梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)
