MATLAB: Switch does not work in GUI

guimatlab function

While running my code through a GUI the SWITCH function does that detect the cases, or maybe it just jumps to the bottom otherwise every time.
contents = cellstr(get(S.element,'String'));
t1 = contents{get(S.element,'Value')};
t = char(t1);
contents = cellstr(get(S.mass,'String'));
u1 = contents{get(S.mass,'Value')};
u = char(u1);
contents = cellstr(get(S.volume,'String'));
v1 = contents{get(S.volume,'Value')};
v = char(v1);
global dens 
switch t 
    case strcmp(t,'Scandium')
        dens = 2.989;
    case strcmp(t,'Yttrium')
        dens = 4.469;
    case strcmp(t,'Selenium')
        dens = 4.809;
    case strcmp(t,'Krypton')
        dens = .003733;
    case strcmp(t,'Neodymium')
        dens = 7.007;
    case strcmp(t,'Antimony')
        dens = 6.685;
    case strcmp(t,'Astatine')
        dens = 7;
    otherwise
        dens = 8.55;
end
Every time it jumps to the other wise option of — dens = 8.55.

Best Answer

You need to convert
switch t
to
switch true
because the value that you give in the "switch" is compared to the values of the "case" statements, and the values of the case statements are the result of the strcmp() and hence are true or false.
Alternately, leave it as "switch t" and remove the strcmp()
case 'Yttrium'
