How do I use one IF-END instead of nested IF-ENDs?

How can I rewrite the following statement so that the nested IF-END structure is not needed. And also replace the code with an IF - ELSEIF - END control structure that accomplishes the same outcome.

if x < y
   if z < 10
        w = x*y*z
   end
else
   w = (x*y*z).^2
end

I think replacing what you have with an IF-ELSEIF structure would make it less efficient because it would result in more comparisons. Is there a particular reason why you want to do this?

if x < y && z < 10
        w = x*y*z;
elseif x>=y
   w = (x*y*z).^2;
end

If that is correct, it always makes 3 comparisons, whereas your original sometimes only makes 1 and at most makes 2.

no particular reason, just working with code and school work

thank you!

w=(x*y*z)^(~((x<y) & (z<10))+1)

Pualo, this is not correct. This will always define w, whereas the IF statements above will not. Specifically, look at x=2,y=4,z=15. This could make a difference where w is defined as a default prior to the IF statement, which has a chance to redefine based on specific conditions.

I knew it wasn't perfect, I tried to add that situation but got tired and distracted by something else, maybe you or other person can improve it.
