Nothing serious.
I forgot to clean the routine, the 4th parameter ( ( double )( DT25 ) ) is not required. Funny that the Matlab Lcc-win32 C 2.4.1 compilator remains quiet about that.
Thanks,

@ Bill
Appreciate you taking the time to respond, I havent went working on it yet…"
Rana replied to Tony's discussion Matrix Nav Issue"Hi Tony !
There is no chance of doubting the MatrixNav 8 & Pitch Roll Yaw Demo 4 firmware.
I have tested both of these firmwares in 2-3 different different planes, including engine powered plane too and found MatrixNav 8 just excellent.
Infact…"

"Tony,
I'll answer both of your questions.
First, with regard to the roll-pitch demo, I assume that you mean the latest version of the roll-pitch-yaw demo.
