matlab初学者对于绘图的基本程序，比如画饼图，线图，向量图，瀑布图等基本绘图基础程序。(matlab for beginners a basic drawing program, such as yourselves chart, line graph, vector, waterfall and other basic drawing foundation program.)

qr算法的matlab代码，利用矩阵的QR分解，逐步按递推法构造矩阵的分解序列的过程，只要原始矩阵式非奇异矩阵，则由QR算法就完全确定其分解序列了(qr algorithm matlab code using a QR decomposition of the matrix, step by step process of the recursive method to construct the matrix decomposition sequence, as long as the original matrix nonsingular matrix by the QR algorithm completely determine the sequence of its decomposition)

使用卡尔曼滤波对加了噪声的GPS定位数据进行滤波。(Calman filtering is used to filter the GPS location data with noise.)

修改后的phase函数，把它的门限值换为pi，使用更方便(The modified phase function, the threshold for it to pi, the use of more convenient)

说明：  ofdm的时域仿真代码，matlab下正常。(ofdm s time domain simulation code with matlab,it s works well.)

用ESPRIT算法对波达方向（DOA）信号进行DOA估计的matlab程序。(ESPRIT algorithm using DOA (DOA) signal DOA estimation matlab program.)

POWER HVDC 12 PULSE OF CONVERTER

提出了一种基于 JPEG/JPEG2000相结合的医学图像感兴趣区域压缩方法。该方法对在人为选定 医学图像的感兴趣区域采用无损的 JPEG2000压缩 ,而对其他图像区域则采用高压缩比的 JPEG压缩,较好地解决了医学图像的高压缩比和高质量之间的矛盾。(Based on a combination of JPEG/JPEG2000 region of interest of medical image compression method. The method of artificially selected region of interest of medical images using lossless JPEG2000 compression, and on other image regions using high compression ratio of JPEG compression, a better solution to the medical image and high-quality high-compression ratio between the contradictions.)

通过该功能，可以处理图像中的很多问题，是图像分析处理的主要工具。(image)
