coeff coefficients of matrix polynomial [C]=coeff(Mp [,v]) Mp polynomial matrix v integer (row or column) vector of selected degrees C big matrix of the coefficients C=coeff(Mp) returns in a big matrix C the coefficients of the polynomial matrix Mp . C is partitioned as C=[C0,C1,...,Ck] where the Ci are arranged in increasing order k = max(degree(Mp)) C=coeff(Mp,v) returns the matrix of coefficients with degree in v . (v is a row or column vector). poly degree inv_coeff
