How to get nan as output if the function output argument is not supported?

I have written a function with three outputs.

function [logical_out, run_time, reaction_time] = reaction_time_function3(~,~,~)
    % code
end

I want run_time and reaction_time output to be 'NaN' if logical_out is 0. How can I do that? In fact, I have written a piece of code not to run the script further if logical_out is 0.

% do not run further calculations if logical ouput is zero
if logical_out == 0
    return
end

if isequal(logical_out,0)
    run_time = NaN;
    reaction_time = NaN;
    return
end

if logical_out == 0
    [run_time, reaction_time]=deal(nan);
    return
end
