May I learn an operator with single input and multiple output with DeepONet?

[fperiago]

Hi all,
I'd like to learn an operator whose input is a number and the outplut a vector. So, if I'm not wrong, the input dimension for the branch net shoud be 1, and the input for the trunk has dimension n>1. The output has dimension n as well.
How can I do it with DeepONet? Is there any example to look at?
Thanks in advance
