Ararat - don't use the elseif and just use two if statements (since you want to apply a specific action to both variables)
if any(isnan(enthleft), 'all');
enthleft = 0;
end
if any(isnan(enthright), 'all');
enthright = 0;
end
By the way, your above code will set all elements of the enthleft or enthright arrays to zero if at least one element is NaN. Is this the intended behaviour?
