Denoising

this file is a matlab program. File name is 2D fast fourier transform.

说明：  EOF为经验正交分解，实现数据的时空分离。是处理气象资料的经典程序(EOF for the empirical orthogonal decomposition, spatial and temporal separation of data. To deal with the classic procedures for meteorological data)

This is a simulation matlab for simulating the process of BCJR decoder that decodes input data s from channel.

平面梁单元算例，比较通用的程序，用来平时计算比较方便(plane beam for computing)

汽车操作动力学的简化2自由度模型，采用Matlab实现。可以实现对汽车的动力学仿真(Automotive operations to simplify the kinetics of 2-DOF model, using Matlab to achieve. Can be achieved on the vehicle dynamics simulation)

本代码的方法是借助旋转不变技术估计信号参数(Estimation of Signal Parameters via Rotational Invariance Techniques)，现已成为谐波恢复（即正弦波个数及频率估计）的一种主要特征分解法。(This code is to help the estimated ESPRIT signal parameters (Estimation of Signal Parameters via Rotational Invariance Techniques), has now become the harmonic retrieval (that is, the number and frequency sine wave estimated) of one of the main characteristics of decomposition.)

说明：  提取图像的颜色特征，首先将图像颜色映射到指定的8个颜色，然后利用自相关和互相关计算得到图像的特征向量，并从原数据库中算出利用此方法检索图像的正确率，并将检索结果好的图像显示到指定文件夹中。(Extract image s color characteristics.First, the image color map to the specified eight colors, then use the auto-correlation and cross-correlation calculation of image feature vectors.and Calculated from the original database, retrieve the images using this method, the correct rate, and a good image display search results to a specified folder.)

这是一个小波变换的程序，滤去噪声实现语音增强(This is a wavelet transform procedures, filter out the noise to realize speech enhancement)

说明：  wisper that is useful for all of the algorithms.

This Matlab program makes a simple QRS detection by the method of Caceres
