Greetings people.
I currently sent some codes for a software that I developed, and I did not take into account that some values ​​could be empty []. I get some empty values and i had to make a sum, but a + [] = []. It was a big mistake.
Is it possible to configure any option to get a + [] = a without using isEmpty or a command?
Thank you in advance.

Thank you Matt.
Do you know if is possible edit the double class or plus function in MatLab?

You should be really careful with editing base components of internal Matlab functions, see this comment for an example why.
Did you try following the advice in the linked pages?
I would strongly suggest using the sum method instead.

You could also replace your plus() operations with sum() operations. Compare:
>> a=3; b=[];
>> a+b
ans =
[]
>> sum([a,b])
ans =
3
