DDC

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.

DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt
