and if in matlab?

Hi,

I want to run an if loop with 2 conditions, but I can't see an "and-if" equivalent.

Eg:

if 0<x<1
*and y2<y1*  
z=y2;
else
end

What operator can I use instead of and?

Thanks,

Richard

There is no such thing as an if loop.

0<x<1 does not do what you want it to!! It is parsed as

(0<x)<1 . 0<x returns a boolean value, 0 or 1, and then that value is tested according to whether it is < 1 which is only the case if the operation was false. The code is thus equivalent to

~(0<x)

and so is the same as

isnan(x) || 0 >= x

I doubt that you would want 0<x<1 to be true when x is nan !!
