Abstract :
A very simple and efficient algorithm called randomised pseudo-skeleton approximation is proposed for the decomposition of a low-rank matrix. The complexity of the algorithm is O(r3), where r is the rank of the matrix. Comparison with the adaptive cross-approximation method is presented to show its validity and efficiency.
