Using socFunctionAnalyzer with methods defined in a class

I am trying to benchmark the performance of a few algorithms each defined in its separate class. Is there a way to run socFunctionAnalyzer for methods defined in a class? I tried creating separate .m files and then passing the class object as a global variable but this is not allowed in socFunctionAnalyzer as well. Are there any ways where I can count the number of addition and mulitplication operations in a class method without having to completely rewrite it?

Hi,

I understand that you would like to compute the number of addition and multiplication operations executed by a method within a class using the "socFunctionAnalyzer" function.

While the "socFunctionAnalyzer" function does not natively accept a class or its methods as direct input parameters, there is a workaround to this. You can implement a wrapper function that instantiates an object of your class and subsequently calls the method in question.

Here's a demonstration of this approach:

1. Define your class and its method in a file named "MyClass.m"

classdef MyClass  
    methods  
        function result = myMethod(obj, input)  
            % Method implementation  
            temp = 0;  
            for i=1:input  
                temp = temp + i;  
            end  
            result = temp*2;  
        end  
    end  
end 

2. Next, create a wrapper function in a separate file, which we'll call "wrapperFunction.m". This function will instantiate an object of "MyClass" and call the "myMethod" function:

function result = wrapperFunction(input)    
    obj = MyClass();  
    result = obj.myMethod(input);  
end 

3. Finally, from the MATLAB Command Window, you can call the "socFunctionAnalyzer" function on the "wrapperFunction.m" file:

socFunctionAnalyzer('wrapperFunction.m',FunctionInputs= {10},IncludeOperator={'+','*'})

This command will generate a report detailing the number of operations in the "myMethod" function. A link to this report will be provided in the Command Window.

Best,

Umang
