An affine combination is a linear combination of vectors in Euclidian space in which the coefficients add up to one.

General motion. A combination of linear and angular movement.

If X1, X2 , ... , Xn are matrices of the same dimensions and a1, a2, ... an are constants, then

Y = a1*X1 + a2*X2 + ... + an,*Xn is a linear combination of the X matrices.
