Exaclty the title.
I know char(177) returns the plus/minus symbol but can't work out how to get it to display when matlab outputs to the command window.
fprintf('The measured volume of %fmm^{3} \x177 %fmm^{3} is equal to\nthe specified volume of %fmm^{3} \x177 %fmm^{3},\nand therefore the object passes quality inspection and can be released.\n',Vtot, DeltVrounded,VSpec,DeltaVSpec);

fprintf(['The measured volume of %fmm^{3} ' pmchar '%fmm^{3} is equal to\nthe specified volume of %fmm^{3} ' pmchar '%fmm^{3},\nand therefore the object passes quality inspection and can be released.\n'], ...
Vtot, DeltVrounded,VSpec,DeltaVSpec);
I'd probably write the format string as a variable to be more readable, but that's just a style nit.
