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 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])
