复指数法是根据结构的自由振动响应或脉冲响应函数可以表示为复指数函数和的形式，然后用线性方法来确定未知参数。其主要思想是从振动微分方程的振型叠加法原理出发，建立动力响应与模态参数之间的关系表达式，通过对脉冲响应函数进行拟合可以得到完全的模态参数，获得了良好的拟合效果。基本方法是以Z变换因子中包含待识别的频率，构造Prony多项式，使其零点等于Z变换因子的值。这样，将求解Z变换因子转化为求解Prony多项式的系数。这里给出用矩阵解Prony多项式的系数的MATLAB程序。()

substitution cipher is the method of encoding in which unit of plain text are replaced by cipher text. Monoalphabetic cipher uses a fixed message over entire message.A monoalphabetic cipher uses fixed substitution over the entire message.The monoalphabetic substitution takes a letter of an alphabet and substitutes it with another letter, this way a ciphertext is generated. The way of converting is fixed. A character of the plaintext will be replaced by the same ciphertext character, during the entire ciphertext. There is no additional key. The only way of security is to keep the substitution-table secret.
A popular example for the monoalphabetic substitution is the caesar cipher.
