how can I define an excel worksheet in Matlab that consider the location of cells with equal numeric values and change them into specific values that I want. in other word I want : Region 1 = locations of all cells with numerical values of A Region 2 = locations of all cells with numeric value of B And so on. and then change each region to specific values that I want. and repeat it and each time changing region s first value to specific values, as many times that I want . each region has so many cells therefor I cant define them cell by cells in matlab.

It's so trivial in Matlab; just import the array; make the changes and rewrite (assuming you must use Excel at all; why can't you just use Matlab?)
data=xlsread('yourfile.xls');
data(data==A)=newA;
data(data==B)=newB;
xlswrite('yourfile.xls',data)
You may have the problem depending on the values addressed in the FAQ--

I don't know about how you're doing the "Excel link to Matlab" specifically, but certainly you'll have to fix any issue of whether the value passed is the character representation (a string/character variable) or the value itself. That should be relatively simple to deal with.
The "firstflg" is a variable you set to know whether the index array needs to be updated or whether to use the previously computed one. It's a local variable to Matlab controlled by whoever is in charge of the overall process which you've yet to describe how this whole thing is structured.
