这是matlab中S函数的编写手册，给想用simulink作控制的提供了一个好的载体。-This is a matlab function in S to prepare manuals, to want to use simulink for control provides a good vehicle.

在matlab/simulink下用S-function实现了用递推最小二乘法的系统在线辨识，对象是开关磁阻电动机，在转矩和转速可测的前提下，得出转动惯量，摩擦系数和负载转矩的在线辨识。-In the matlab/simulink using S-function realization of the recursive least squares method using the system online identification, the target is switched rel

Matlab S-Function Lecture,very Good!m Code to Simulink module.
