Webrcond is a more efficient, but less reliable, method of estimating the condition of a matrix compared to cond. Algorithms The algorithm for cond has three pieces: If p = 2, then cond uses the singular value decomposition provided by svd to find the ratio of the largest and smallest singular values.
