simulink Embedded MATLAB Function

[hameeds01]

Hello everyone
I would appreciate if someone could help me, I am using “Embedded MATLAB Function” block in Simulink matlab, the problem is that I want to store the previous values of the variables that I am using in Embedded MATLAB Function block just like M-file code secondly I want to make them appear in workspace How I can do that ??

Why dont you use MATLAB function?

It is more closer to matlab syntax

Faster than embedded

Reliable for computing

And you can define its variables in workspace using global type variables

i don't know how to use MATLAB function can u plzzz show me some example

 

[gsecer]

function [fnc2]=fnc2(M)

global fnc2;
global T;
global Jg;

fnc2=M*T/Jg;

end

This is a simple example. fnc2 output M input

Global adjective means variables are stored in workspace. If your output or input ports are vector, there is no need for change the syntax in first line.

For different rows of vector you can use fcn2(1),fcn2(2)... etc.
