Assuming your array has multiple rows and one column ...

        m = find (a > 0.25);

If your array has multiple rows and columns, the rows with one or more elements 
larger than 0.25 ...

        m = find (any (a.' > 0.25));

If you want the rows and columns for elements larger than 0.25 ...

        [m, n] = find (a > 0.25);
