Direct Linear Transformation (DLT) Solver

The script solves a general projective linear system.

The DLT technique solves for a m-by-n transformation matrix A given X a n-by-k matrix containing many column vectors in n-dimensional space and Y the transformed vectors in m-dimensional space following Y ~ AX, where ~ denotes projective equality, i.e. both sides are equal up to a scale. The solution is normalised to guarantee the uniqueness.
