Help: 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

Thank you so much. Your answer makes me more understood about using if condition. Actually, I want to show both 'a&b~=c' and 'a~=c' and I found that I have to use each if-end with each expression. It will be as:

   if c==2
      disp('C=2')
   end
   if a~=c && b~=c
       b~=c
          disp('a&b~=c') % Statement 3
   end
   if a~=c
          disp('a~=c') % Statement 2
   end

And the command window will show both statement 2 and 3.

Thanks again man.
