this is matlab codes for t-norms

各种不同信号调制方式的matlab源程序(Various signal modulation matlab source)

spatial channel model

simulation of a single phase PWM inverter

contains Rectifier circuits for both single phase and three phase with various types of switches, pulse generator input remains same for all, an additional circuit with an active filter which can be used to reduce harmonics if the pulses are given by a paticular procedure.

根据经纬度计算两点间的球面距离（两种方法基于球面余弦公式，基于Haversine公式）、计算方位角。(calculate spherical distance and azimuth angle by Latitude and Longitude)

快速弦截法进行工程整定，反复迭代直到满足工程要求(Secant method works fast tuning iteratively until meet the engineering requirements)
