MATLAB: Embedded matlab block as a parameter – not an input (without “ports and data manager”)

embedded matlab codeMATLABparameterports and data managersimulinkworkspace

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!
Dave

sorry, I just found this:
coder.extrinsic('evalin')
fixed_step_size = evalin('base', 'fixed_step_size');
