DCT

用MATLAB实现的计算器 用的是GUI制作的 (Realized by MATLAB using a GUI calculator produced)

matlab code for audio compression

本程序实现轨迹生成。基于的原理是飞行器位置和姿态解耦，对其进行独立设计，通过反解出惯性器件信息，从而用于导航。(The program trajectory generation. Based on the principle of the aircraft position and attitude decoupling its independent design, the inverse solution inertial devices used for navigation.)

基于Matlab的脉冲编码调制(PCM)系统设计与仿真(Based on Matlab pulse code modulation (PCM) system design and simulation)

In this paper, we consider the use of Modulation Spectra for voice pathology detection and classification. To reduce the high-dimensionality space generated

这个算法通过matlab仿真得到的最小生成树Prim算法(Matlab simulation of the algorithm obtained Prim minimum spanning tree algorithm)

说明：  X线管电压对X线穿透能力的影响 X线穿透随管电压变化的曲线(X-ray tube voltage on the penetration of X)

无约束多维极值问题的描述，提供了几种解决方案(very good)

说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

对图片做二维dct变换，每一小块为8*8(Do the 2-D DCT transform , every piece of 8*8)
