根据牛顿插值原理进行数据的拟合，附有牛顿插值原理和它的matlab的实现方法，有点简单了，但是过程中的好些地方还是值得学习的。(Newton interpolation carried out in accordance with the principle of data fitting, with Newton interpolation matlab principle and its realization method, a bit simple, but in the process of a number of places it is still worth learning.)

MATLAB版本的最短路径算法dijkstra的实现。自己写的(MATLAB versions of the shortest path algorithm dijkstra implementation. Their written)

u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )
