Type, the following at the MATLAB command prompt:
initialDataGuess = { 30, 60, 20 };   % qA, qB, qC.     
initialDataActual = MGFourBarInitialValues( initialDataGuess{:} );  
qA = initialDataGuess{  1 };                                       
qB = initialDataActual( 2 );                                       
qC = initialDataActual( 3 );
