这是一个超分辨率重建实现的pocs算法，运行成功通过，得到预期的实验结果。(This is a super-resolution reconstruction algorithm to achieve the pocs run successfully, to achieve the expected results.)

说明：  图像置乱中的仿射变换，优点是加密和解密的不需要周期迭代，图像置乱效果好(it is good for image scrambling becaus of low compute complexity)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.
