MATRIX DECOMPOSITION FOR RENDERING ADAPTIVE AUDIO USING HIGH DEFINITION AUDIO CODECS

A method of decomposing a matrix of dimension L-by-N, where L is less than or equal to N, into a sequence of N-by-N unit primitive matrices and a permutation matrix comprising a sequence that is the product of the primitive matrices and the permutation matrix, containing L rows that are substantiall...

Zusammenfassung:	A method of decomposing a matrix of dimension L-by-N, where L is less than or equal to N, into a sequence of N-by-N unit primitive matrices and a permutation matrix comprising a sequence that is the product of the primitive matrices and the permutation matrix, containing L rows that are substantially close to the provided L-by-N matrix, where the choice of the permutation matrix and the indices of the non-trivial rows in the primitive matrices are chosen to limit the coefficient values in the primitive matrices.
