w=input('enter the weight ')
material=input('enter type of material ','s');
material=lower('material');
f1=0.2*w;
f2=0.35*w;
f3=0.4*w;
f4=0.7*w;
switch material
case 'mmetal'
disp(f1)
case 'wwood'
disp(f2)
case 'mwood'
disp(f3)
case 'rcon'
disp(f4)
otherwise
disp('error')
end
it is jumping to otherwise line
and can we use mathematical operation and display that result under 'case' section
i.e for example
case mm
force =w*0.3

material=lower(material); without the single quote.
