"How to use for loop in this problem"
The main problem I can see is forcing pseudo-indices into variable names. Once beginners start trying to access those variable names dynamically then they force themselves into writing slow, complex, inefficient code trying to access their data:

Basically your bad data design will force you into writing bad code.
What do you think is the problem?

Maybe this helps.
tbl = array2table(b);
tbl.b1
tbl.b2
tbl.b3
% see also tbl.Properties
