ldiv polynomial matrix long division [x]=ldiv(n,d,k) n,d two real polynomial matrices k integer x=ldiv(n,d,k) gives the k first coefficients of the long division of n by d i.e. the Taylor expansion of the rational matrix [nij(z)/dij(z)] near infinity. Coefficients of expansion of nij/dij are stored in x((i-1)*n+k,j) k=1:n arl2 markp2ss pdiv
