Dear all, Could you help me? I have this matrix: A= [1 3 0 2 0 0 3 0 0 4 3 0 5 0 0 6 0 0 7 0 0 8 0 0 9 0 0 10 3 0 11 0 0 12 0 0 13 5 0 14 0 0 15 0 0 16 0 0 17 6 0 18 0 0 19 0 0 20 0 0 21 3 0 22 0 0 23 0 0 24 6 0 25 0 0 26 0 0 27 0 0 28 0 0 29 0 0 30 0 0 31 0 0 32 0 0.02256 33 0 0.018682 34 4 0.011892 35 0 0.022345 36 3 0.018794 37 0 0.021655 38 0 0.015674 39 0 0.023075 40 0 0.01055 41 0 0.013921 42 3 0.017497 43 0 0.023766 44 0 0.005467 45 0 0.011991 46 0 0.020437 47 0 0.022869 48 0 0.014035 49 0 0.023253 50 0 0.019731 51 0 0.019275 52 0 0.012172 53 0 0.010395 54 0 0.01569 55 0 0.014506 56 0 0.011423] I want to extract a submatrix which have number 0 in the columm 3. The result will be B=[1 3 0 2 0 0 3 0 0 4 3 0 5 0 0 6 0 0 7 0 0 8 0 0 9 0 0 10 3 0 11 0 0 12 0 0 13 5 0 14 0 0 15 0 0 16 0 0 17 6 0 18 0 0 19 0 0 20 0 0 21 3 0 22 0 0 23 0 0 24 6 0 25 0 0 26 0 0 27 0 0 28 0 0 29 0 0 30 0 0 31 0 0]and another submatrix which have all range with number 3 in the second columm. The results will be:C= [1 3 04 3 010 3 021 3 036 3 0.01879442 3 0.017497]. Thanks.
