中文说明：这个文件是关于分数阶余弦变换的MATLAB代码和分数阶傅里叶变换MATLAB代码，可以用于图像处理加密、滤波等用途，一维的变换实测在即接近整数时会有较大差距，可能算法比较旧，二维的变换没用过，可能和一维的由类似的问题，如果有需要的可试一下，最近我在做关于分数阶傅里叶变换的工作，希望能够交流一下
English Description：
This file is about the fractional cosine transform matlab code and fractional Fourier transform matlab code, can be used for image processing encryption, filtering and other purposes, one-dimensional transformation measurement will be close to the integer there will be a big gap, the algorithm may be relatively old, two-dimensional transformation has not been used, and one-dimensional transformation may be caused by similar problems, if you need to try, I recently in Do on the fractional Fourier transform work, hope to be able to exchange
