Do I need to scale an Inverse Matrix by it coefficient

    Hello,

    http://www.summitinstruments.com/knowledge_center/pdf/TN413.pdf

    So I have had a go at implementing the math on page 1 of the attached document and it
    seems to work. I say seems to work because the way that I gather the accelerometers calibration values (offset and scale) may not be perfect hence I could be introducing my own small errors. Also I only have a limited set of test data ( R at different static orientations) to test with.

    My question is:

    Do I need to scale the matrix T or B by the coefficient of T to get the correct/best answer?

    I ask as when I do scale B by its coefficient the error size is smaller.

    I measure the error by 1 - |R| = error size.

    Many thanks in advance
