Getting Matrix Row Values Back After Repeating Values Vector Has Been Calculated

I have a problem in which I have to find the repeating values in a matrix and then get the values of a row for which the values were repeating. I have completed the first part where the repeating values are fed into the vector valCount. I am not sure how to follow the second part in which I have to get the values of a row for which valCount >=2.

range_devices = 
    0     0     0
    0     0     1
    0     0     1
[row,col] = find(range_devices);
A = [row col];                                                       
uniqueVals = unique(A(:,1));                                                
valCount = hist(A(:,1), uniqueVals)';
