Function 'assignin' not supported for code generation.

i am currently tring to debug a model and to do this i want to see what values are being fed into the matlab function block in simulink, i've tried using display blocks but they don't update when the error occurs so i tried to add an assignin command in the funtion block to send the inputs to the workspace to view but i keep getting this error. does anyone know another way to view the inputs?

Globals. Which requires registering a datastore https://www.mathworks.com/help/simulink/ug/using-global-data-with-the-matlab-function-block.html but inside a MATLAB Function Block you can code in terms of the standard global directive (you just have to register the MATLAB Function Block in the port manager.)
