matlas v0.7.0

Changes

• Allow WorkspaceScope and MatFile handles to coexist through shared Matlab borrows.
• Reject property access, generic MAT-file writes, and full-value MAT-file reads while a workspace value is borrowed.
• Add PlainArrayRef and MatFile::put_plain for direct MAT-file writes of numeric, logical, and character arrays, including supported sparse arrays. Cell, struct, string, and object arrays are excluded.
• Document the callback audit and add MATLAB integration coverage for guarded operations and v7.3 primitive writes.

Validation

Passed cargo test --workspace --locked, Clippy with warnings denied, rustdoc with warnings denied, Rust 1.77 workspace build, cargo package --locked, API coverage audit, and the MATLAB R2024a integration suite (156 array-direction checks across five formats).

matlas v0.6.0

matlas v0.6.0

• Convert MATLAB character rows and scalar string values to Rust text with ArrayRef::to_text, preserving Unicode and embedded NUL characters and rejecting missing strings.
• Read and create logical scalars with ArrayRef::logical_scalar and Matlab::logical_scalar.
• Receive fixed callback outputs through Matlab::call_array::<N> and WorkspaceScope::call_array::<N>.
• Set validated MATLAB exception identifiers with Error::with_id.
• Declare fixed MEX argument counts with Inputs<'mex, N> and Outputs<'mex, N>; inputs.into_array() supports array destructuring. Existing variable-count handlers remain supported.

Compatibility: Error now has a private identifier field, so construct errors with Error::new instead of a struct literal.

Validated with the full MATLAB R2024a integration suite, Rust 1.77.0 build, Clippy, docs, API coverage audit, and cargo package --locked.

matlas v0.5.0

Workspace pointer handoff

• Add Matlab::workspace_scope, WorkspaceScope::get, and consuming WorkspaceScope::call so multiple mexGetVariablePtr values can be passed to MATLAB without a Rust-side array copy.
• Accept ordinary ArrayRef inputs alongside workspace values in callback argument order. Reject a callback while an unused workspace value remains live.
• Replace Matlab::workspace_borrow and WorkspaceRef with the scope API.

Validation

Rust tests, Clippy, docs, API coverage audit, and cargo package --locked passed. The MATLAB integration suite passed on R2024a, and the workspace built with Rust 1.77.0.

matlas v0.4.0

First release under the matlas name. Provides ownership-aware Rust APIs for MATLAB R2025a Matrix, MEX, and MAT-file interfaces. Validated on Windows with MATLAB R2025a; building requires MATLAB headers and libraries.
