Programs about interval matrices


  Main programs (the input mu must be given as the two matrices m and M, containing respectively the minima and the maxima of the entries of mu):
  • rk01: for any interval matrix mu, it says if mrk(mu) is 0, 1 or greater than 1;
  • mrkpx3: for any interval matrix mu with 3 columns, it calculates mrk(mu);
  • rkmax: for any interval pxp matrix mu, it calculates if Mrk(mu)=p.

    Auxiliary programs:
  • reduce: it reduces the interval matrices, that is eliminates from the interval matrix [m,M] the rows containing (0,....,0) and the columns containing the transpose of (0,...,0)
  • multisubsets: mutisubsets(p,k) calculates the k-multisubsets of {1,...,p}; each is given in lexicographic order
  • orderedmultisubsets: orderedmultisubsets(p,k) calculates the ordered k-multisubsets of {1,...,p}
  • rk1nnr.m: given a reduced interval matrix mu with entries contained in the set of the nonnegative real numbers, it says whether mu contains a matrix with rank 1;
  • sist: it says whether a systems as in Corollary 16 of the paper is solvable;
  • rklesseq2: given a reduced interval p x 3-matrix mu with the entries of the first column contained in the set of nonnegative real numbers, the program says whether mrk(mu) <= 2.
  • nondegpgdiag: the program gives the totally nondegenerate pg diagonals of length k of an interval square matrix [m,M]; precisely it gives a matrix U such that the first half and the second half of every row are the indices of a totally nondgenerate pg-diagonal of [m,M]
  • scelta: given a matrix X and a column Y the program gives a matrix whose rows are all the rows obtained taking a row r of X and adding to it an element e of Y if e is not element of r
  • sceltabis: given an array of columns Y, the program gives a matrix U whose rows are obtained by taking an element a1 from Y(1), then an element from Y(2) different from a1 and so on
