How rotate a cube f1 to its edges are parallel to another cube (f2) ?
I have two 3 dimensional orthogonal sets of the 1444 observation in each.
julia> size(f1)
(1444,3)
julia> size(f2)
(1444,3)
cor in each are real 0,
julia> cor(f1)
3x3 Array{Float64,2}:
1.0 -2.39743e-16 3.8112e-16
-2.39743e-16 1.0 -2.02954e-16
3.8112e-16 -2.02954e-16 1.0
julia> cor(f2)
3x3 Array{Float64,2}:
1.0 -5.55883e-17 1.76522e-17
-5.55883e-17 1.0 1.70523e-15
1.76522e-17 1.70523e-15 1.0
There are also orthogonal: angle in degrees matrix of f1
3x3 Array{Float64,2}:
0.0 90.0 90.0
90.0 0.0 90.0
90.0 90.0 0.0
angle in degrees matrix of f2
3x3 Array{Float64,2}:
0.0 90.0 90.0
90.0 0.0 90.0
90.0 90.0 0.0
but angle in degrees betwen f1 and f2 are:
90.6388 91.4539 88.8789
92.2294 90.6144 89.2666
88.8462 89.6773 92.377
angle in degrees betwen f2 and f1 are:
90.6388 92.2294 88.8462
91.4539 90.6144 89.6773
88.8789 89.2666 92.377
How rotate one of the cube to edges f1 are parallel to f2 ?
first col f1 parallele to first col of f2 . etc...
