How to set manualy matrix coordinates in DNG4PS-2. I can set it in "matrix" field in settings of course, but finally coordinates in DNG are invalid. For example I set properly values  A720 (from dcraw) :
 
1.4573 -0.5482 -0.1546 -0.1266 0.9799 0.1468 -0.1040 0.1912 0.3810

and after conversion check DNG file by dnggetmatrix - I have wrong values: 
  
1.4886 -0.5600 -0.1579 -0.1293  1.0010 0.1500 -0.1062  0.1953  0.3892.

I can try to add differences between values or substract but no succes :(.
I can use dngsetmatrix, but why waste time ?
Any ideas, please ?

DNG4PS-2 normalizes matrix when saving DNG file (DNG library does it). Normalized matrix has same effect for colors as with original matrix.
