Version:
    Last Modified: March 15, 2017

    Returns a lower bound for the 1-norm condition number of a square matrix.

    Syntax

    c = condestimate(a)
    c = condestimate(a, b)
    [c, d] = condestimate(a)
    [c, d] = condestimate(a, b)
    Legacy name: condest

    Inputs

    a

    Square matrix.

    b

    Positive integer.

    Outputs

    c

    Lower bound for the 1-norm condition number of a.

    d

    Approximation of a null vector. d is a vector of the same size as the number of columns in a.

    A = [1, 2, 3; 0, 1, 1; 4, 3, 1]
    D = condestimate(A)
