Variable in Text [Matlab]

Hi Team!

I havea brief question. I would like to use variable as below:

branch_ego.step.step"i".branch"j"

It's going to be like branch_ego.step.step1.branch1, branch_ego.step.step1.branch2, branch_ego.step.step2.branch3 etc.

How can I implement variable to the text variable ?

Thanks !

You can use dynamic fieldnames:

Although using indexing would be simpler and more efficient:

You don't! Numbered variables are always a bad idea. Instead you use indexing:

branch.ego.step.step(i).branch(j) = ...

See why variables should not be named dynamically for all the reasons why your initial request is a very bad idea.
