C code version of Matlab function fir1.m (lowpass only)

this matlab script simulates Havriliak-Negami, Cole-Cole,Debye,Cole-Davidson fitting functions by comparing the numerical curves to experimental curves. The experimental database is selected by the program from a matrix in a text file

最小方差恢复算法，用于恢复图像中未知位置的点像素(Minimum variance recovery algorithm, used to restore the image point of the unknown location of the pixel)

with or without modification, are permitted provided that the following conditions are met

说明：  matlab实现运动模糊图像的模糊长度的自动鉴别(Matlab implementation of motion blurred image fuzzy length automatic identification)

波阈值去噪，比较了软阈值，硬阈值及当今各种阈值计算方法和阈值函数处理方法的性能，通过信噪比及均方差的比较，得出各种的算法的优劣(Wave threshold denoising compared soft threshold and hard threshold and the current calculation method and the various thresholds threshold function processing performance of the method by SNR and mean square deviation of the comparison, the pros and cons of various algorithms)

An extra file fdct_usfft_path.m is included in fdct_usfft_matlab directory. This script needs to be called to append several subdirectories into the searching path.

这是个labview的互相关程序 包含了好几子VI 在实际的信号处理中 效果很好(This is the inter-related procedures LabVIEW contains several sub-VI in the actual signal processing well)

检测从键盘输入字符。用到了fiugre的 currentcharacter 属性，figure还有一个 currentkey 属性。这两个属性都能检测键盘输入，不过还是有不小区别，可以试一下。(Detection input from the keyboard characters. Use of the fiugre' s ' currentcharacter' property, figure there is a ' currentkey' property. These two properties can be detected keyboard input, but there are still no small difference, you can try.)

利用自然梯度算法来对于5 类信号进行盲信号分离，采用自然梯度法对混合的信号进行 分离并分析其性能，并比较不同步长对于信号分离的影响(Use of the natural gradient algorithm for the five types of signals blind signal separation, using the natural gradient method for mixed signal Separation and analysis of its performance and compare sync signal separation for the impact of long)
