For example I have the following cell
   x1 x2 x3
x1  2  3  4
x2  5 -2 -5
x3 -6 -5 -4
I want to search all variable of matrix > -2, and as output : x1, x2 for example. In my case :
INPUT:find(matrix>-2),
OTUPUT:
X1 X1
X1 X2
X2 X1
X1 X3

        I wasn't sure if you want the actual output in terms of 'x*' or the corresponding index.
 >> inputMat = [2 3 4; 5 -2 -5; -6 -5 -4];
 >> [myRow, myCol] = find(inputMat > -2);
 >> numericalAns = [myRow myCol];
 >> indexNames = {'x1' 'x2' 'x3'};
 >> cellFormAns = [indexNames(myRow)' indexNames(myCol)'];

			Is this what you're looking for?
 >> matchValues = inputMat(inputMat > -2);
