CG

说明：  it just a simple code in matlab for image zooming

说明：  Regression sum of squares , the maximum deviation , minimum deviation , the average deviation

这是学习matlab的非常实用的程序Matport是NTPort Library的MatLab接口模块。借助Matport，你可以在Matlab中直接访问PC 的I/O端口。(Before use Matport, your must install the latest version of NTPort Library. And copy all files of Matport into MatlabWork directory. Start Matlab, and now you can use matport command to call NTPort Library functions. The basic syntax of Matport is as follows, matport( NTPort Library funtion , parameters...) For example, if you want to call Inport function to read a port, simply use myvalue = matport( Inport , 97) Port address 97 is as a decimal.)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

很好用的Dijkstra求最短路的MATLAB程序，带注释，都能看懂。。。。(Find a good use of the Dijkstra shortest MATLAB programs, with comments, can understand. . . .)
