MATLAB: Simplify a string with MATLAB script

Question

Hello !

I have a string format which looks like this (this is not always 'A' before '_' and numbers) :

Eq = 'A_1+((A_2+A_3)&(A_4+A_5))+A_6';

How can i simplify the string like this (with a script) :

Eq = 'A_(1+((2+3)&(4+5))+6)'

For me the simplest way would be to delete all 'A_' iteration except the first one and to add a '(' after the first 'A_' but i don't know how to do it in a script.

Thank you in advance for your help !

Edit : After Stephen answer review, i realized i missed a detail : sometimes the string can be like this :

'A_number_1+((A_number_2+A_number_3)&(A_number_+A_number_5))+A_number_6';
==> 'A_number_(1+((2+3)&(4+5))+6)'

With multiple string for example : 'String_String_String_1' . Is there anyway to delete string and '_' behind a number ?

>> Eq = 'A_1+((A_2+A_3)&(A_4+A_5))+A_6';
>> Fq = regexprep(Eq, '^([A-Z]+_)(.*)', '$1\(${strrep($2,$1,'''')}\)')
Fq =
A_(1+((2+3)&(4+5))+6)
