[dependabot-preview]

Updates the requirements on ndarray-rand to permit the latest version.

Changelog

Sourced from ndarray-rand's changelog.

Version 0.12.0 (2018-09-01)

• Add var_axis method for computing variance by @LukeMathWalker.
• Add map_mut and map_axis_mut methods (mutable variants of map and map_axis) by @LukeMathWalker.
• Add support for 128-bit integer scalars (i128 and u128).
• Add support for slicing with inclusive ranges (start..=end and ..=end).
• Relax constraint on closure from Fn to FnMut for mapv, mapv_into, map_inplace and mapv_inplace.
• Implement TrustedIterator for IterMut.
• Bump num-traits and num-complex to version 0.2.
• Bump blas-src to version 0.2.
• Bump minimum required Rust version to 1.27.
• Additional contributors to this release: @ExpHP, @jturner314, @alexbool, @messense, @danmack, @nbro

Version 0.11.2 (2018-03-21)

• New documentation; @jturner314 has written a large “ndarray for NumPy users” document, which we include in rustdoc. Read it here a useful quick guide for any user, and in particular if you are familiar with numpy.
• Add ArcArray. RcArray has become ArcArray; it is now using thread safe reference counting just like Arc; this means that shared ownership arrays are now Send/Sync if the corresponding element type is `Send
  • Sync`.
• Add array method .permute_axes() by @jturner314
• Add array constructor Array::ones by @ehsanmok
• Add the method .reborrow() to ArrayView/Mut, which can be used to shorten the lifetime of an array view; in a reference-like type this normally happens implicitly but for technical reasons the views have an invariant lifetime parameter.
• Fix an issue with type inference, the dimensionality of an array should not infer correctly in more cases when using slicing. By @jturner314.

Version 0.11.1 (2018-01-21)

• Dimension types (Ix1, Ix2, .., IxDyn) now implement Hash by @jturner314
• Blas integration can now use gemv for matrix-vector multiplication also when the matrix is f-order by @maciejkula
• Encapsulated unsafe code blocks in the s![] macro are now exempted from the unsafe_code lint by @jturner314

Version 0.11.0 (2017-12-29)
