i have an array in a loop:
use{i,1}=strrep(use{i,1},statename{j,1},xx{1,j})
the idea is to find precise statenames and repacle them with xx
but its doing parts.
how do i use the lookbefoe and after idea here, with no ' 'in the code?

Do not use strrep for this: use regexprep with lookaround operators.

use{i,1}=regexprep(use{i,1},['(?<=[^a-zA-Z,0-9])',statename{j},'(?=[^a-zA-Z,0-9])'],xx{1,j});

Are you sure comma to be part of the list? Those are literal comma not range separators.
