COMBVEC Create all combinations of vectors. <a href="matlab:doc combvec">combvec</a>(A1,A2,...) takes any number of inputs A, where each Ai has Ni columns, and return a matrix of (N1*N2*...) column vectors, where the columns consist of all combinations found by combining one column vector from each Ai. For instance, here the four combinations of two 2-column matrices are found. a1 = [1 2 3; 4 5 6]; a2 = [7 8; 9 10]; a3 = <a href="matlab:doc combvec">combvec</a>(a1,a2)
