This paper describes implementation of the Discrete Cosine Transform(DCT) algorithm to MATLAB. This approach is used in JPEG or MPEGstandards for instance. The substance of these specifications is toremove the considerable correlation between adjacent picture elements.The objective of this paper is not to improve the DCT algorithm itself, but to re-write it to the preferable version for MATLAB thusallows the enumeration with insignificant delay. The method proposed inthis paper allows image
