Scientific scripts can now pass numeric data between matrix operations and statistics without manual reshaping. Explicit
row,col, andmatconstructors validate complete shapes; numerical list operations accept lists, rows, and columns consistently, including mixed integer/float samples.dotcomputes a scalar vector inner product, whilemtimesperforms matrix multiplication.Regression results expose the fitted intercept so callers can reconstruct predictions. A bundled CSV example covers predictor construction, fitting, prediction, and residual diagnostics. The change also fixes numeric extrema indices, preserves integer precision in integer statistics, restores minimal-feature compilation, and limits Polars to its supported 0.45 CSV API.
The README stays concise, with detailed conventions in a linked workflow guide. Package metadata and the changelog prepare version 0.4.0, including migration notes for Rust matrix-helper callers. Publishing is a separate step.
Validation: 25 minimal-feature, 50 numerical-feature, and 304 full-feature tests passed locally (counts include Rust documentation tests); the CSV regression example, formatting checks, and all-feature publish dry run passed. CI exercises all three feature configurations.
