MATLAB: Help: if condition with evaluating multiple statements

if condition with evaluating multiple statements

Hi everybody,
My sample if condition have 3 expression. As the following code, how can I evaluate statement 2 and statement 3 when the expressions are true?
a=1
b=1
c=3
if c==2
    disp('C=2')
elseif a~=c
    disp('a~=c') % Statement 2
elseif a~=c && b~=c
    disp('a&b~=c') % Statement 3
end
When I run the code, it just showed 'a~=c', eventhough the expression 'a~=c && b~=c' is true.
Thanks.

Khanh, only one of the if ( elseif ) statements is executed. In your case it is the second one, because it is the first condition that evaluates true.
Use instead:
 if c==2
    disp('C=2')
 elseif a~=c
    if b~=c
        disp('a&b~=c') % Statement 3
    else
        disp('a~=c') % Statement 2
    end
 end
