Hi.I created a m.file that define a variable resistor.I want to use this variable resistor in a simulink file in simpower system.my m.file is : if(current>160) R=log(current) else R=0 end 'current' is a signal in my simulink file.I need to run this m.file in Same time with my simulink.thus R can be a variable resistor in my simulink file.how can i do it?please help me.

Hi Mischa.I saw this link.but in this topic,the parameters have a constant value.but in my project, 'R' is a function of current and changes continuously.

I see. In this case you might want to use an embedded MATLAB function. In the Simulink library browser go to > Simulink > User-Defined Functions and select a MATLAB function block. Embedded MATLAB function are, as the name implies, automatically and directly integrated in(to) a Simulink model.
