class Butterflypack(CMakePackage):
"""ButterflyPACK is a mathematical software for rapidly solving
large-scale dense linear systems that exhibit off-diagonal rank-deficiency.
These systems arise frequently from boundary element methods, or
factorization phases in finite-difference/finite-element methods.
ButterflyPACK relies on low-rank or butterfly formats under Hierarchical
matrix, HODLR or other hierarchically nested frameworks to compress,
factor and solve the linear system in quasi-linear time. The
computationally most intensive phase, factorization, is accelerated via
randomized linear algebras. The butterfly format, originally inspired by
the butterfly data flow in fast Fourier Transform, is a linear algebra tool
well-suited for compressing matrices arising from high-frequency wave
equations or highly oscillatory integral operators."""
