Sorry in the above I put 2 t*s^2 in the column vector, I'm now wondering if maybe I make that column vector and the row vector two 3x3 matrices and use the tensor product if that makes A something nicer...
I found this matrix way of writing it, but I'm not entirely happy with it unless maybe someone happens to know if this matrix A is used somewhere else:
If you want to have something you can copy and paste into a math program you can use this:
p = 1.0*((1/4)*b-(1/2)*s*b+(1/2)*s*s*b+(1/2)*t*t*d+(1/2)*t*d+(1/4)*e+(1/4)*g+
t*t*s*s*((1/4)*g+(1/4)*b+(1/4)*d+(1/4)*e)-(1/2)*t*t*s*g+(1/2)*s*s*g+...
I guess I should have explained that Q in the above can be any of the X,Y,Z values it's the same formula for each, I've looked at some of the General Relativity formulas and it looked to me like it's a lot of effort to keep all the coordinate axis straight, this formula is the same for each...
I found this formula for doing a quadratic conformal map with parameters:
I think there's probably a nice Einstein notation representation of this above but I haven't figured it out yet.. But anyway the mapping is like below:
I don't know enough about General Relativity to know how this...
