Callback and evalin

Hi, my code :
function [] = P_call(varargin)
P = varargin{3};
X = get (P.po, 'value');
model_path = 'D:\MATLAB\GUI\';
scenarios_path = [model_path 'Scenarios\'];
scenarios_p = dir([scenarios_path 'TS_Sy_MooN_P_*.m']);
if ~isempty(X)
evalin('base', 'load(''default_values'')');
evalin('base', 'run(''scenarios_p(X).name'')');
evalin('base', 'run(''import_ch_inputs'')');
% sim('MooN_simu_1_2');
end
close(gcbf)
My problem : I don't know how to run this :
evalin('base', 'run(''scenarios_p(X).name'')');
Matlab don't know scenarios_p(X) etc, and I understand why, but I don't know what can I put to replace this, anybody...?
Thanks.

Also, not sure if you are aware of this, but you can have the Simulink model resolve variables in the caller workspace instead of the base workspace
outp = sim('MooN_simu_1_2','SrcWorkspace','current');
This might help you avoid having to do all these base workspace assignments

Just to be clear, your solution allow running Simulink from within a function and accessing all variables in the function's workspace, right? I haven't been able to do this previously, so this could be helpful.

The evalin is evaluating the argument X in the workspace but X only exists in your current function, try like this
evalin('base', ['run(''scenarios_p(' num2str(X) ').name'')']);

When you add parameters to a Simulink model, the model tries to resolve those parameters in the MATLAB base workspace.
When you call "sim" from within a function, it can be difficult if you still are allowing Simulink to resolve parameters in the base workspace. This is because your function has to use evalin or assignin to modify the base workspace.
Alternatively, you can define everything in your function workspace from within your function, and then call sim like I have shown to get Simulink to resolve parameters to your function workspace.
Does that make sense?
