Since you have the plane (not only the normal vector), a way to find a unique rotation matrix between two coordinate system would be: do the non-unique rotation twice! ##That is Find an orthogonal vector in the same plane of interest with AA and BB respectively. Say Ao⊥AAo⊥...
x = Pb [x]b: we call Pb the change-of-coordinates matrix from B to the standard basis in R^n. Let B and C be bases of a vector space V. Then there is a unique n*n matrix P_C<-B such that [x]c = P_C<-B [x]b. The columns of P_C<-B are the C-coordinate vectors...
In linear algebra, the inputs and outputs of a function are vectors instead of scalar. Assume we have a coordinate system e1,e2 and that (x1x2) is the coordinate for the vector x. We can now have a function y=F(x) that maps every x to a new vector y=(y1y2) according to, fo...

half of nineteenth Century, because if when work reached its culmination in.1888, Peano axiomatically defined finite or infinite dimensional vector space. Toeplitz will be the main theorem is generalized to arbitrary body linear algebra on the general vector space. The concept of linear mapping can...
线性代数课件 chapter1 Linear Equations in Linear Algebra.ppt,Example : let T: R2→R2 be the transformation that rotates each point in R2 about the origin through an angle , with counter clockwise rotation for a positive angle. We could show geometrically
3D coordinate system Det is volumn, sign apply right-hand rule, some times computations does not fall within the essence of linear algebra, prove take some effort, but if view geometrically it's natural composite area just same each area multiply, it's not official prove but it's give us...
