COEFFS_CONJ2FULL

Contents

function [Coeff_full] = coeffs_conj2full(Coeff_part,row_idx,col_idx, ordering, type)
        

Transform coefficients from reduced conjugate to full representation

This function computes the full coefficients with ordering specified in the input array with the same name, given the coefficients in conjugate ordering up to the conjugate center index. It is used in a cellfun of conj2lex as well for the autonomous computation.
