Public Functions

inline DenseMatrix(): Create an empty dense matrix.

inline DenseMatrix(size_t rows, size_t cols)

Create a dense matrix with specified number of rows and columns

Parameters:

rows – Number of rows
cols – Number of columns

inline DenseMatrix(size_t rows, size_t cols, TYPE intitial_value)

Create a dense matrix with specified number of rows and columns and initialize the element to a given value

Parameters:

rows – Number of rows
cols – Number of columns
intitial_value – Value to initialize the matrix elements with

inline size_t Rows() const: Return the number of rows.

inline size_t Columns() const: Return the number of columns.

inline void Set(TYPE val): Set the elements of the matrix to a specified value.
