If we have two individually sorted vectors "a" and "b" but they are not sorted with respect to each other and we want to merge them into vector "c" such that "c" is also a sorted vector. Then c=mergesorted(a,b) can be used. (If we have two vectors individually sorted "a" and "b" but they are not sorted with respect t o each other and we want to merge them into vector "c" such that "c" is also a sorted vector. Then c = mergesorted (a, b) can be used.)

用MATLAB实现图像的离散余弦变换，程序运行结果表明离散余弦变换能够起到压缩图像的目的。(in order to compress the bite of pictur,the program use the DCT to compress.)
