I would like to know whether the MATLAB Function block created in Simulink can be programatically check or parameters of the function can be obtained.
For example

y = fcn(u) or y = FunctionName(u)

I would like to get the function name fcn or FunctionName

How are you hoping to use this information if it's available? What are you planning to use it for?

It's for a custom Simulink Check

Finding the function line is easy because it's the first line that starts with "function". Just need to deal with the different possibilities for the function signature.

For example, to find the function line

config = get_param(gcb,'MatlabFunctionConfiguration');
fline = strip(split(string(config.FunctionScript),newline));
fline = fline(startsWith(fline,"function"))
fline = fline(1);

fline =

"function img = fcn(lambd,m,n)"

% assign to fline here to see rest of processing to find the function name
fline = "function img = fcn(lambd,m,n)";
% this logic for typical signature: function (outputlist) = fcn (inputlist)
if contains(fline,"=")
    fline = extractAfter(fline,"=")
    if contains(fline,"(")
        function_name = strip(extractBefore(fline,"("))
    end
end
fline = " fcn(lambd,m,n)"
function_name = "fcn"
