Hi
i have a S-function block that works perfectly fine when i didnt feedback it as an input for the S-function.
When i feedback my results to the s-function, it comes out a algebraic loop error or the output becomes 0. What i want is just used the calculated value from the S-function block for the next time step.
Is there any other methods to get what i want other than looping back the value?

Problem solved by using the unit delay block.
