hi i have this matrix :
Loudness=[2.79;3.16;3.71;2.29;2.49;2.64;2.9;2.79;2.91;3.35];
FlucStr=[0.0256;0.0277;0.0311;0.0246;0.021;0.0199;0.0194;0.0256;0.0213;0.0208];
Roughness=[0.491;0.6;0.728;0.34;0.425;0.515;0.617;0.491;0.389;0.438];
Sharpness=[1.03;1.11;1.21;0.887;0.934;0.954;0.985;1.03;1.04;1.12];
Leq=[39.7;40.9;42.6;38.1;38.9;39.5;40.6;39.7;40.3;41.7];
SIL=[29.4;30.9;32.9;26.9;28;28.8;30.1;29.4;28.8;30];
Tonality=[0.133;0.128;0.113;0.153;0.14;0.131;0.118;0.133;0.203;0.18];
Kurtosis=[2.2;2.2;2.2;2.44;2.49;2.48;2.45;2.2;2.39;2.38];
subjective=[7.5;7.02;6.94;7.91;7.96;7.91;7.78;7.42;7.86;7.47];
metriche=[Loudness FlucStr Roughness Sharpness Leq SIL Tonality Kurtosis];
and i need to select with the command for loop 2 every combination of column vectors like:
Loudness FlucStr, Loudness FlucStr , Loudness Roughness, Loudness Sharpness, Loudness Leq, Loudness SIL , Loudness Tonality, Loudness Kurtosis,
FlucStr Roughness, FlucStr Sharpness, FlucStr Leq, FlucStr SIL, FlucStr Tonality, FlucStr Kurtosis, ......................ecc

use nchoosek to get all the pairs:
Loudness=[2.79;3.16;3.71;2.29;2.49;2.64;2.9;2.79;2.91;3.35];
FlucStr=[0.0256;0.0277;0.0311;0.0246;0.021;0.0199;0.0194;0.0256;0.0213;0.0208];
Roughness=[0.491;0.6;0.728;0.34;0.425;0.515;0.617;0.491;0.389;0.438];
Sharpness=[1.03;1.11;1.21;0.887;0.934;0.954;0.985;1.03;1.04;1.12];
Leq=[39.7;40.9;42.6;38.1;38.9;39.5;40.6;39.7;40.3;41.7];
SIL=[29.4;30.9;32.9;26.9;28;28.8;30.1;29.4;28.8;30];
Tonality=[0.133;0.128;0.113;0.153;0.14;0.131;0.118;0.133;0.203;0.18];
Kurtosis=[2.2;2.2;2.2;2.44;2.49;2.48;2.45;2.2;2.39;2.38];
subjective=[7.5;7.02;6.94;7.91;7.96;7.91;7.78;7.42;7.86;7.47];
metriche=[Loudness FlucStr Roughness Sharpness Leq SIL Tonality Kurtosis];
pairList = nchoosek(1:8,2);
for ii = 1:size(pairList,1)
thisMatrix = metriche(:,pairList(11,:)) % dispaly to screen
end

can i do this with 3 or 4 or all vector column?

to get all combinations of 3 columns, use nchoosek(1:8,3)
to get all combinations of 4 columns, use nchoosek(1:8,4)
