I also do not really understand why the vector should be a problem. Btw my 
ind2sub in the example is completely superflous. Doug Stewart already gave the 
simpler syntax which does the same, since find is clever enough to output the 
right result when called with two result parameters

[i, j] = find(A==val)

which is less noisy. I somehow did not notice that before.
