problem for loop matrix

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];

metriche=[Loudness FlucStr Roughness Sharpness Leq SIL Tonality Kurtosis];

i want to select with the command for loop, every combination of 2 vector column like:

[Loudness FlucStr] [Loudness Roughness][Loudness Sharpness][Loudness Leq][Loudness SIL][LoudnessTonality][Loudness Kurtosis]

[FlucStr Roughness][FlucStr Sharpness][FlucStr Leq][FlucStr SIL][FlucStr Tonality][FlucStr Kurtosis].......etc
