how to simulate a resistor?

ok so i want to build a matlab function block to do something(emulating a variable resistor and control quantity of that by a specific algorithm) and also i want to connect it to a PV array. it seems these two blocks (MATLAB function and PV array) wont connect to gather. any suggestion? also my plan B will be a variable resistor which its quantity determined by MATLAB function block. unfortunately there is not a variable resistor for PV array (SimPowerSystem). really need some suggestion and help.. tanx

Hi Mohsen! Well, technically it depends which output/input signal you would like to connect to a MATLAB function block. Input Signals lr, T and the output signal m is a Simulink signal. Therefore you can connect it to a MATLAB function block. The other two ports (+ and -) are physical signals. These can only be connected to electrical connector port. The MATLAB function block does not have these kinds of ports. Regarding your question on how to implement a variable resistor I would like you to take a look at the following link: https://de.mathworks.com/matlabcentral/answers/92766-how-can-i-create-a-variable-resistor-for-use-in-simpowersystems

Have a great day,
