MATLAB读取cad生成的dxf文件,在MATLAB可以处理简单的CAD的对象，为MATLAB读取cad提供了一种方法。(MATLAB can read the file of dxf. You can do opertion to the object in the cad.)

读取语音信号 对语音信号进行分帧 加窗 傅立叶变换 并且实现倒谱(Read the speech signal of the voice signal framing windowed Fourier transform and the realization of cepstrum)

使用Matlab编程实现发送端信源编码（图像压缩）和接收端信源解码（图像重建），其中的编解码算法可采用基于DCT变换的JPEG图像压缩标准；测试图像加噪，然后对去噪后的图像进行压缩与重建，分析压缩性能；研究基于下采样和内插的图像压缩算法；可将8bit/pixel灰度图像扩展至24bit/pixel彩色图像，或者采用无损压缩算法对图像压缩。(Sender using the Matlab programming source coding (image compression) and the receiver source decoding (image reconstruction), one of the decoding algorithm can be used DCT-based JPEG image compression standard test image with noise, then the denoised image compression and reconstruction, compression performance analysis of down-sampling and interpolation based on image compression algorithm 8bit/pixel grayscale images can be extended to 24bit/pixel color images, or the use of lossless compression algorithms for image compression. )

在原有matlab程序的基础上增加一个功能即原有程序在未统计之前，一个数默认频次为一，但是这个可以在频次不为1的情况下统计总的频次(Add a function on the basis of the original matlab program that is not before the original program statistics, a number of default frequency is one, but this can count the total frequency in the frequency is not a case)

说明：  一段用来做数值计算的代码，主要是做的数值模拟，用来模拟流线形态的代码()

利用最小方差方法估计复正弦加白噪声得平稳信号的功率谱(After using the method of minimum variance estimate sine smooth white noise to the signal power spectrum)
