MATLAB: Error: Function definition not supported in this context. Create functions in code file.

errorfunctionmatlab function

Hello,

I was trying to create a simple function on matlab, I already have a file named "AddOne.m", so it should work, however at the first line of code, matlab throws the following error

"Error: Function definition not supported in this context. Create functions in code file.". Any ideas how to sort this out?

Thanks in advance!

Hi Augstin,

In matalb, you need to write your function in a seperate matlab file and then you can call this function either from command window or from a seperate matlab file.

For example, here you can write your matlab function addOne.m in one file. File content can be something like:

%File addOne.m
function finalAnswer = addOne(inputNumber)
    finalAnswer = inputNumber+1;
end

Now you can use this function in your other matlab file or in command window. For example, you can create a seperate file to call this function.

% File testaddOne.m
inputNumber = 5;
finalAnswer = addOne(inputNumber);
disp('Thining...');
fprintf('Final Answer: %d \n', finalAnswer);
display('Done');

To avoid confusion, for now keep both files at one place. When you run file testaddOne.m, it will automatically call other file and make use of it.

Cheers.

MATLAB: How to access function from a different scipt

That error message is correct. If you have a function inside a script file, the name of the function must not be the same as the name of the script. This is documented in the Note in the "Syntax for Function Definition" section on this documentation page.

As stated on this other documentation page functions in script files are not normally accessible outside that script file. If you want that function to be accessible one of the following must be true. [I don't think I missed any possibilities, but if I did these are the most common ways to make a function in a file accessible to the Command Window and other files.] The first is probably the easiest.

The function needs to be the main function in a function file (not a script file)
The script file needs to create a function handle to the function
The function file in which it is a local function needs to return a function handle to that local function, or
The function needs to be a method of a class

MATLAB: Using fminsearch on a Function with Multiple Outputs

It is not possible to use an anonymous function to select a particular output from a function. You need to use an actual function.

   function result = lastoutput(fun, varargin)
     n = nargout(fun);
     outs = cell(1,n);
     [outs{:}] = fun(varargin{:});
     result = outs{end};

And now you can

out3min = fminsearch( @(x)lastoutput(@calculateValues,x,a), x0);
