 However, while iterative solutions to the problem are generally simultaneous and accurate, they can be computationally taxing to carry out and may not always converge on the optimal solution.The matrix equation , where is unknown, has an infinitive number of solutions that can be easily studied by a geometrical approach.To find it is necessary to consider a simultaneus set of 2 equations and ; the matrices have to be dermined by experiments to be performed in an optimized way.
