这段代码主要是实现二阶巴特沃斯高通滤波器，本段代码全部用MATLAB语言实现的。(This code is to achieve second-order Butterworth high-pass filter, the above code to achieve the full use of the MATLAB language.)

利用MATLAB语言，实现分时电价的功能，程序里面有清晰的注释(realize the TOU function)

A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.
