Hello,
I have a syntax question. I would like to use the set_param function to define a callback Startfcn of a simulink block. How can I put an argument to my Startfcn function ?
For example : modelName = 'sim_model.mdl' function_name = 'start_function' set_param(modelName,'StartFcn',function_name);
For example, my Startfcn is like this :
function start_function(abc) display(abc) end
Thnak you in advance.

Where you want to put 'StartFcn' callback function, either for a block or for a whole simulink model ?
For StartFcn of a block:
Get the block handle and use with set_param(). For example
bh=gcbh; % Returns handle of current selected block
set_param(bh,'StartFcn',function_name);
For StartFunc of whole model:
Get the model handle and use with set_param(). For example
open_system(modelName);
mh=get_param(modelName_without_extension,'handle'); % Retuns model handle
set_param(mh,'StartFcn',function_name);
-------------
[ EDITED ]
abc_str=sprintf('%f',abc) % Get the value of abc in string
func_str=strcat('start_function(',abc_str,')');
set_param(mh,'StartFcn',func_str);
You can format string 'abc_str' as per data type of variable 'abc' using %d, %s etc.

I have to again guess how your structure will be.
Please give some datails. If you can not post original data, express it with examples.
