说明：  matlab语言编写的 大地电磁电阻率正演程序(matlab language MT resistivity forward procedure)

图像的放大缩小，其中缩小任意比例，放大整数比。在matlab的work路径中选择需要操作的图像，图像使用者自备。(Image Zoom, which reduce the arbitrary ratio to enlarge than integer. In matlab choose the path of work need to operate images, user-owned images.)

第四版prokias数字通信配套源代码之大结局（从第10章一直到书本末）(source code(matlab )for prokias Digital Communication (4th edition))

These sources help to solve problems on numerical methods

很好的一本书，适合初学者，尤其对想要用matlab实现与计算机互动的人很重要。(A good book is suitable for beginners, especially to want to use matlab and computer interaction people is very important.)

图像网格的计算方法，包括快速算法，优于Normalized算法(Image grid computing, including fast algorithm, Normalized algorithm is superior)

EOF分解，用ncdisp命令可以看到HadISST_sst.nc是1870年1月至最近的全球SST数据，按比例截取北太平洋（20N-80N 130E-90W）1971年1月至1990年12月240个月份的SST数据进行经验正交函数（Empirical Othorgnal Function）分解,简记为EOF分解，得到该区域该时段的海温时空特征。(EOF decomposition, with ncdisp command can see HadISST_sst.nc is January 1870 to the recent global SST data, in proportion to the interception of the North Pacific (20N-80N 130E-90W) 1971 年 1 月 至 1990 年 12 月 240 month SST data, empirical orthogonal function (Empirical Othorgnal Function) decomposition, abbreviated as EOF decomposition to obtain spatial and temporal characteristics of sea surface temperature in the region of the period.)
