用matlab求两个向量的相关函数，可以直接执行(Using matlab for the correlation function of two vectors can be directly executed)

is the code in sample in matlab

Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.

可以实现有效数字、杨氏模量及牛顿环等计算(Can achieve significant figure, Young s modulus and the Newton s rings and other computing )

This code would calculate the approximate root of any polynomial using Newton Raphson Method

rapresents AR(1) model. dsp and correlation funtion of the ar(1) MODEL. it uses randn to generate vector and filter to do ar(1).
