Use an 'auto' variable from the script in the matlab to simulink solver

Hello,
I would like to modify my simulink solver parameters from an input file loaded by a matlab script.
I would like to modify my simulink solver parameters from an input file loaded by a matlab script. When I add floating numbers, the solver launches without any problem. But if I want to specify in this file the 'auto' function available on Simulink, Simulink does not recognize the variable. Is there a way to give him this information from a workspace variable?
For example this script.m fill in the Simulink solver don't work :
solver.max_step_size = 5e-1;
solver.min_step_size = 5e-3;
solver.initial_step_size = 'auto';
solver.relative_tolerance = 1e-3;
solver.absolute_tolerance = 'auto';
Thnkn for your help,

Yes. This is a problem. A Mathworker might be able to explain why it is done this way. I can provide a workaround solution.
In your script.m, add a line after every parameter that is a string/char array (not a numerical number). For example
solver.initial_step_size = 'auto';
set_param('ModelName','InitialStep', solver.initial_step_size);
Click Help in Configuration Parameters dialog or see this page for the name of the parameters
