I do not know why my if function is giving me all my outputs, can someone help? function [butterAmount]=howMuchButter(toastThickness, toastArea) if (toastThickness = 0.5 && toastThickness = 9); butterAmount='medAmnt'; elseif (toastThickness >0.75) && (toastArea >16); butterAmount='largeAmnt'; else butterAmount='tooWeird'; end end

Why is my if function not working?

I do not know why my if function is giving me all my outputs, can someone help?

function [butterAmount]=howMuchButter(toastThickness, toastArea)
   if (toastThickness < 0.5) && (toastArea<9);
          butterAmount= 'smallAmnt';
      elseif (toastThickness >= 0.5 && toastThickness <= 0.75) && (toastArea <= 16 && toastArea >= 9);
          butterAmount='medAmnt';
      elseif (toastThickness >0.75) && (toastArea >16);
          butterAmount='largeAmnt';
      else
          butterAmount='tooWeird';
      end
  end

Attach the test code also to make it easy for us to run. What is "zyLab's MATLAB"? How is that different from the regular MATLAB that we run?

You are running the function four times, each time asking that the output be assigned to a variable and that the results be displayed (because you do not have a semi-colon on the end of the line asking to not display output). Four outputs is the expected answer.
