本工具箱描述了非线性盲源分离的原理及算法(This toolkit described the principle and algorithm of nonlinear blind source separation)

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.

导体的电感　电容　特性阻抗曲线　的ＭＡＴＬＡＢ模拟(Conductor inductance capacitance characteristic impedance curve of the MATLAB simulation)

Convert from latitude, longitude, and altitude (geodetic with respect to the WGS-84 ellipsoid) to a position vector in the Earth-centered, Earth-fixed (ECEF reference frame.

本程序可计算主应力大小和方向。主应力就是两个垂直方向的作用力的合力所产生的力在单位截面上的力。(This program can calculate principal stress size and direction. Two vertical principal stress is the force by the force of the force in the direction of force on cross section in the unit.)
