Changelog

• Unreleased - Fixed a compilation regression in csmat_binop - Bump MSRV (1.64) - add support for reading/writing Complex{32,64} matrices in matrixmarket format.

  Also change semantics so that files of kind {integer,real,complex} are only readable into matrices of the same kind (so integer can be read into [iu]{8,16,32,64,size}), real into u{32,64}, complex into Complex{32,64}. And raise a meaningful error if the user tries something that produces a mismatch.

  Also make skew-symmetric and symmetric matrices work for complex values.

  • add support for reading hermitian complex matrices in matrixmarket format. Of course, reading non-complex hermitian matrices is nonsensical, so this raises an error (on the off-chance that some other matrixmarket writer can write such matrices).

• 0.11.0 - MulAcc is generalised to allow different output types from input - Bump ndarray to 0.15. This requires a bump in MSRV to 1.49

• 0.10.0 - support more scalar types for scalar/matrix multiplication - refactor the handling of CsMatBase's indptr member to be able to

  express correct slicing views over the outer dimension breaking change
