PROPACK

| Documentation | Linux/macOS/Windows/FreeBSD | Coverage | DOI | |:-----------------:|:-------------------------------:|:------------:|:-------:| | docs-stable docs-dev | build-gh build-cirrus | codecov | doi |

A Julia interface to PROPACK, a library for the computation of the truncated singular value decomposition of real (Float32, Float64) and complex (ComplexF32, ComplexF64) matrices or linear operators. PROPACK only requires operator-vector products to estimate singular values and singular vectors.

How to Cite

If you use PROPACK.jl in your work, please cite using the format given in CITATION.bib.

How to Install

julia julia> ] pkg> add PROPACK pkg> test PROPACK

Version 0.5.0 of PROPACK.jl requires at least Julia 1.8.

Examples

Compute leading singular triplets

julia U, s, V, bnd, nprod, ntprod = tsvd(A, k=3) # 3 largest singular values and their singular vectors

Compute leading singular values only

julia s, bnd, nprod, ntprod = tsvdvals(A, k=3)

Compute smallest singular triplets

Make sure A is square or short and wide to avoid the trailing zero singular values:

julia U, s, V, bnd, nprod, ntprod = tsvd_irl(A, k=2)

Compute smallest singular values

julia s, bnd, nprod, ntprod = tsvdvals_irl(A, k=2)
