COEFFS_LEX2REVLEX

Contents

function [cell_revlex] = coeffs_lex2revlex(cell_lex,string)
        

Transform ordering between lexicographic and reverse lexicographic ordering

Converts input coefficients from lexicographic ordering to reverse lexicographic ordering (and also reverse)

order = numel(cell_lex);
