eckit::linalg::Matrix class
#include <eckit/linalg/Matrix.h>

Dense matrix in column major storage order.

Public types

Matrix(): Default constructor (empty matrix)
Matrix(Size rows, Size cols): Construct matrix with given rows and columns (allocates memory, not initialised)
Matrix(const Scalar* array, Size rows, Size cols): Construct matrix from existing data (does NOT take ownership)
Matrix(Stream&): Constructor from Stream.
Matrix(const Matrix&): Copy constructor.
~Matrix(): Destructor.

auto operator=(const Matrix&) -> Matrix&
void swap(Matrix&): Swap this matrix with another.
void resize(Size rows, Size cols): Resize matrix to given number of rows/columns (invalidates data)
void setZero(): Set data to zero.
void fill(Scalar): Fill vector with given scalar.
void encode(Stream&) const: Serialise to a Stream.
