problem with anonymous function in executable

I have a three files that work perfectly. However when I compile them matlab behaves as if I didn't include one of the files even though it is included in the deployment.

    function testMain

    kuzu = zeros(5,1);
    anonymousFunction = testClass.anonymousFunction;
    kuzu2 = anonymousFunction(kuzu)

    end

    classdef testClass
        properties (Constant)
            anonymousFunction = @(x) replaceZeroWithNaN2(x)
        end
    end

    function output = replaceZeroWithNaN2(input)

    input(input==0) = NaN;
    output = input;

    end

All the files are in the same directory. After compilation I get the following error:

Undefined function 'replaceZeroWithNaN2' for input arguments of type 'double'

While I don't have a explanation of why you are seeing this error, I have a suggestion to rewrite your code.

Generally function handles are useful in context of algorithms | | , i.e. sort algorithm needs a comparator etc, integration algorithm needs a value of function at a point (x,y) etc.

For all other purposes I recommend using static methods : see examples of static methods .

Can you rewrite your code to make ' replaceZeroWithNaN2 ' a static method of class ' testClass ' and see what happens? I assume the codegenerator will have a easier time resolving that symbol.

Goodluck.

Using static methods seem to work. So is there some instability in the way code generator handles anonymous functions?

Glad to know this worked for you Emre.

I encourage you to still file a customer report with Mathworks technical support.
