I have never heard Matrix H, but gather that it was as good or as bad as other quad systems. The Wikipedia article has an informative section on Matrix H (written by members of this list). In the third reference of that section you will find BBC Research Report 1977/2 which gives the decoding equations for both a linear (fixed) decoder and a logic (variable) decoder. http://en.wikipedia.org/wiki/Quadraphonic sound#Matrix_H http://downloads.bbc.co.uk/rd/pubs/reports/1977-02.pdf The fact that they had to use a logic decoder suggests that the linear decoding didn't work very well. The supposition that linear decoding doesn't work very well suggests that it was not a very good system.
