公司最近项目做的一个DDC（数字下变频）simulink建模模型 真情奉献给大家(this is a project about digital down-converter,it is bulit with Simulink.)

A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems get a short check value attached, derived from the remainder of a polynomial division of their contents on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match.

Design and Use of Steerable Filters PAMI1991文章的代码，含有测试图像和demo，可运行(It implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H. Adelson, "The Design and Use of Steerable Filters", IEEE PAMI, 1991.)
