Hi everyone,
I'm trying to pass a value from workspaces to Simulink calculated by Matlab step-by-step. This value changes each step, but the Simulink simulation take the first value and keep it costant. I'm using simin block and doesn't refresh data. How can I solve this issue?

How is value changing in base workspace? Are you running a loop which changes the value of the variable?

If the value is continually changing in the base workspace, you need to use MATLAB function block and evalin() to read the updated value at each time-step. See the attached file (saved in R2020a). It reads the value of variable 'x' from base-workspace.
