## Version 1.0.0

$\underset{j}{max}\sum _{i=1}^{n}|{a}_{ij}|$
of an $n×n$ matrix $A$ given the ability to multiply a vector by both the matrix and its transpose. Because the explicit form of $A$ is not required, the subroutine can be used for estimating the norm of matrix functions such as the inverse. Additionally this subroutine is potentially useful for estimating condition numbers of a matrix when the matrix is sparse or not available explicitly.
