+//! # Simple Dense Matrix
+//!
+//! Implements [`BaseMatrix`](../../trait.BaseMatrix.html) and [`BaseVector`](../../trait.BaseVector.html) for [Vec](https://doc.rust-lang.org/std/vec/struct.Vec.html).
+//! Data is stored in dense format with [column-major order](https://en.wikipedia.org/wiki/Row-_and_column-major_order).
+//!
+//! Example:
+//!
+//! ```
+//! use smartcore::linalg::naive::dense_matrix::*;
+//!
+//! // 3x3 matrix
+//! let A = DenseMatrix::from_2d_array(&[
+//!            &[0.9000, 0.4000, 0.7000],
+//!            &[0.4000, 0.5000, 0.3000],
+//!            &[0.7000, 0.3000, 0.8000],
+//!         ]);
+//!
+//! // row vector
+//! let B = DenseMatrix::from_array(1, 3, &[0.9, 0.4, 0.7]);
+//!
+//! // column vector
+//! let C = DenseMatrix::from_vec(3, 1, &vec!(0.9, 0.4, 0.7));
+//! ```
