I have created a Simulink model that takes variables (constants) from the Workspace. Within the Simulink model I have added a Matlab function that recalculates these constants after each iteration. However, after each iteration, instead of considering the newest value calculated for each variable, the model takes again the value I set from the Workspace in the beginning. Any idea on how I can update my values each step?
Thanks, Omar

You can also use the 'IC' block (Initial Conditions).

The variables you are updating might be local to your MATLAB function.
Consider defining the variables in the MATLAB function as persistent or global . This might resolve the issue where the changes being made to the variables are not reset.
