Dear All:
I have a row vector of a=[375.7,515.3,432.3,530.7,454.4,490.7,503.4,449.9,509.0,447.2,474.2,398.3,410.6] and I want to select 3 random values for all possible combinations without a repetition.
Could anyone help me with this case? Thanks.
With my best regards,
Mohammed

Read about nchoosek.
P = [375.7,515.3,432.3,530.7,454.4,490.7,503.4,449.9,509.0,447.2,474.2,398.3,410.6] ;
idx = nchoosek(1:length(P),3) ;
iwant = P(idx)
