说明：  信号频谱分析，倍频程算法matlab程序，1/N倍频程(Signal spectrum analysis, octave algorithm matlab program, 1/N octave)

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.

自治系统Poincare映射的计算方法，附有程序以及算例。运行庞加莱里面的“zhixing.m”文件即可。(Autonomous system Poincare mapping method of calculation with procedures and examples are given. Run Poincaré inside zhixing.m files.)
