what is the error here? It is showing "Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters."

You have split your equation over two lines without telling MATLAB. You must add an ellipsis at the end of the first line to indicate the two lines are to be read together.
See here.
ea=(abs(A(ma_i,ma_j)- ...
A_old(ma_i,ma_j))/abs(A(ma_i,ma_j)))*100;
