步进电机的MATLAB仿真程序，采用了卡尔曼滤波，对定子电流进行估计，并估算出转子的位置和速度(Continuous time extended Kalman filter simulation for two-phase step motor，Estimate the stator currents, and the rotor position and velocity, on the basis of noisy measurements of the stator currents. )

In numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.(The secant iteration to find the zero of some non-linear function converges to zero if appropriate starting values are chosen. Although the convergence rate is not as good as the one of the Newton method, it may sometimes converge when Newton fails. The funtion should be defined as an inline function and two starting values are required to start the iteration. Please enter help secant from the Matlab prompt for usage information and examples. )
