Get reduce the size of an original sound file between half to three quarters of the initial size. The FLAC format is often used to sell music online, and as an alternative to MP3 to share when you want to reduce the file size would have

估计Hilbert矩阵的2条件数和矩阵的阶数的关系用Gauss消去，分别用Gauss消去，Jacobi迭代，Gauss-seidel迭代，SOR迭代和共轭梯度法求解，比较结果。(Discuss the 2 condition number of the matrix and the matrix order relations.Using different methods like Gauss，Jacobi，Gauss-seidel，SOR and GS)

随机样本的生成和概率密度函数的绘制，课程作业~希望能有所帮助~(Generates a random sample drawn and probability density function of the course work, hope to be able to help ~ ~)

仿真采用QPSK和16-QAM调制时，接收机采用理想信道估计和利用训练符号进行信道估计的误比特率性能(The simulation using QPSK and 16-QAM modulation, receiver with perfect channel estimation and using training symbols for the bit error rate performance of the channel estimation)

采用DIT和DIF两种蝶形算法实现的FFT变换，其中myfft1是DIT算法，myfft2是DIF算法，已经过测试，可以方便使用。(DIT and DIF using two algorithms of FFT butterfly transformation, which myfft1 is DIT algorithm, myfft2 is the DIF algorithm, has been tested, it will be convenient to use.)

插值算法，具体使用方向为高斯插值，Kriging插值可以参考(Interpolation algorithm, the specific direction of the Gaussian interpolation, Kriging interpolation can refer to)

一个matlab的处理图像的函数的电子书，使用方便，可以搜索，非常实用(A matlab image processing function of the e-book, easy to use, you can search, very useful)

常见的潮流程序主要采用直角坐标来进行，本程序采用极坐标对简单输电网系统潮流进行计算(Common trend of the procedure used mainly for rectangular coordinates, polar coordinates, the program uses a simple grid system to calculate the trend)

对信号进行EEMD分解，比原先的EMD效果更好，能够分解出较好的本征模函数(EEMD the signal decomposition, works better than the original EMD, better able to factor out the intrinsic mode function)
