For example, if we start at the top left corner of our example graph, the algorithm will visit only 4 edges. To compute the time complexity, AX = B by some method." e.g. solve it by A nB or by rst computing the LU factorization of A and then using it to solve AX = B. One reason that you don’t usually compute inverse matrices is that it is wasteful: once you have PA = LU, you can solve AX = B directly without bothering to … A fast LU factorization of linear complexity is developed to directly solve a dense system of linear equations for the capacitance extraction of any arbitrary shaped 3-D structure embedded in inhomogeneous materials. In addition, a higher-order scheme is developed to achieve any higher-order accuracy for the proposed fast solver without sacrificing its linear computational complexity.
