Respected Sir,

I am trying to define 3 fuctions and function is selected based on random numbers with equal probabilities. How can I define the functions?

For instance,

out = randsrc(1,1,[1,2,3;(1/3),(1/3),(1/3)]); % used to choose between 1,2,3 based on equal probability.
if out==1
    function calculation1(arguments)
    %calculation
    elseif out==2
        function calculation2(arguments)
            % calculation
        else
            function calculation3(arguments)
                % calculation
            end
        end
    end
end

在 MATLAB Online 中打开

switch randi(3)
    case 1
        y=calculation1(arguments);
    case 2
        y=calculation2(arguments);
    case 3
        y=calculation3(arguments);
end
function y=calculation1(arguments)
  %your calculations
end
function y=calculation2(arguments)
  %your calculations
end
function y=calculation3(arguments)
  %your calculations
end
