Embedded matlab block as a parameter - not an input (without "ports and data manager")

Hello,

When using an embedded Matlab block within Simulink, I would like to make the use of parameters more transparent by including definition of ports in the function i.e

function [ ...
    ... % Signals controlling stimulus
    output_arg1                 ,...
    output_arg2                 ]...
    = Sequencer(                 ...
    ... % From Test Bench
    time_in                     ,...
    stop_time                   ,...
    fixed_step_size             ,...
    ... % From UUT
    input_arg1                  ,...
    input_arg2)

    % Function code

end

Where "fixed_step_size" is not an input port to the block but instead takes the value from the workspace - the value in the work space will not change over the duration of the simulation.

At the moment I am using the "ports and data manager" but this is not obvious when reviewing code.

so the question is: Is there a way to get a workspace parameter from the workspace - within the Matlab code, without using the ports and data manager?

Many thanks!

sorry, I just found this:

coder.extrinsic('evalin')
fixed_step_size = evalin('base', 'fixed_step_size');
