returning an empty array if statement

Hi there I am kinda new to programming.

I am attempting to solve a question which is checking if 2 fields are empty and if they are return an empty array:

for example if I wanted to calculate the third side of a tiangle as long as a and b were present i could calculate c. if a or c are = 0 then I would need to return an empty array. so far I have:

if a && b == 0

not much I know but its a start haha

>if a or c are = 0<

sorry a and b are 0

if isempty(a) || isempty(c)
  yourOutputArg = [];
  return;
end
% else continue with the rest of your function's code.

Looks like Aadam doesn't really mean "empty" for a and b.

if a == 0 || b == 0

This could also be coded as

if any([a,b]==0)

or, more obscurely,

if ~all([a,b])
