v0.3.0

MatrixAlgebraKit v0.3.0

Diff since v0.2.5

Changelog:

• Added support for CUDA and ROCm through extensions -- currently QR, LQ, and SVD are supported on GPU
• Added support for svd_trunc! on GPU including randomized SVD from CUDA
• Added support for generalized eigensolving (CPU only)
• Modified check_input to allow algorithm-specific checks
• Added gaugefix function for eigensolving and SVD

Merged pull requests:

• WIP CUDA support (#20) (@Jutho)
• Add generalized eigenvalue decomposition, fix some bugs (#39) (@kshyatt)
• Bump actions/checkout from 4 to 5 (#40) (@dependabot[bot])
• [WIP] Attempting to wrap randomized SVD (#41) (@kshyatt)

v0.2.5

MatrixAlgebraKit v0.2.5

Diff since v0.2.4

This release features the new isisometry(A; kind=:left), isisometry(A; kind=:right) and isunitary functions to conveniently verify whether or not A' * A = I and/or A * A' = I.

Merged pull requests:

• Add isisometry function and integrate into tests (#38) (@lkdvos)

Merged pull requests:

• Make select_algorithm more agnostic about being in the object or type domain (#32) (@mtfishman)

v0.2.1

MatrixAlgebraKit v0.2.1

Diff since v0.2.0

Merged pull requests:

• Refactor algorithm selection in type domain (#30) (@lkdvos)

Closed issues:

• Add the algorithm as an argument to truncate! for more customization (#27)
• Allow specializing default_algorithm/select_algorithm on the matrix type (#29)

v0.2.0

MatrixAlgebraKit v0.2.0

Diff since v0.1.2

Breaking:

• More general truncation and algorithm selection in orth/null functions. Specifically, truncation in left_orth!/right_orth! and left_null!/right_null! are now specified through a trunc keyword argument that can accept any arguments that svd_trunc! accepts, and algorithms of each backend can be customized with the associated keyword arguments alg_qr, alg_svd, etc. (#19).
• Change the by and rev inputs of truncrank from args to kwargs (#22).

Non-breaking:

• Refactor algorithm selection logic (#23).
• Make orthnull more customizable and general (#25).
• Support unsorted spectra in TruncationKeepAbove/Below (#26).
