The spectral properties of special matrices have been widely studied, because of their applications. We focus on permutation matrices over a finite field and, more concretely, we compute the minimal ...

C Permutation Matrix Encryption (CPME) is a proof of concept encryption algorithm which uses matrix multiplication to permute, or reorder, data stored in a byte-array. For encryption, the program ...

One particular example would be a matrix that has 0's everywhere except for one 1 in every column and every row. This is called a permutation matrix.

In this paper, a simple but efficient permutation enhanced parallel reconstruction architecture for compressive sampling (CS) is proposed. In this architecture, a measurement matrix is constructed ...

Permutation factor circulant matrices have been applied widely in numerical computation, signal processing, coding theory and oil investigation in recent years, and so on. In this paper, we present a ...
