Dear all,
I calculate PI parameters which are Kc, Ti in a function block. But later, I want them to use just as gain block. How can i do this? As you know, i can only use the output part of the fcn block. Can i use the calculated variable just like a gain? Thanks.

Use a Multiply block from the 'Math Operations' library. One input is the signal that needs to be increased in magnitude. The other input is the gain value from the MATLAB Function block.
Please note that the multiply block is listed as 'Divide' in the library.

Is there a reason you did not add an input to the function block, do the multiplication in the code within it and then produce an output signal? That was you have a custom gain block that calculates the PI parameters. You could also a mask on this block using which you could tune parameter values (like you change the gain value on a Gain block).
