HP50G : TRN vs TRAN

Perhaps it has to do with the fact that originally all matrix operations were directly taken from the ones already implemented in Saturn assembly language for the HP-71B Math ROM and there the conjugate transpose was named TRN.

Also, for complex matrices the conjugate transpose is by far the most useful operation as compared with just the transpose alone, which almost never appears in any algorithm or real-life application.
