MATLAB: Niggle with a “simple” if-else structure.

Question

Hi.

I want to enforce the following structure in MATLAB –

if a>20

{Statement set 1}

elseif 10<a<20

{Statement set 2}

else

{Statement set 3}

end

`a' can take only positive values, from 1 to 30.

My syntax for `elseif' might be wrong, but atleast in this post it clarifies what I'm trying to do :

1) if a > 20, execute statement set 1.

2) if a lies between 10 and 20, execute statement set 2.

3) if a < 10, execute statement set 3.

The problem is, it executes statement set 2 even if a < 10, probably because 10<a<20 is not allowed as an elseif condition.

Is there any other way of enforcing this structure in MATLAB? Or, can someone please suggest a correct `elseif' condition for this purpose.

Thanks.

Answer 1

Instead of

elseif 10<a<20

do the following:

elseif ( (a>10) && (a<20) )
