`GF2::Matrix` — Size Queries

How many rows, columns, elements etc. are in the bit-matrix?

constexpr std::size_t rows() const;       (1)
constexpr std::size_t cols() const;       (2)
constexpr bool is_square()   const;       (3)
constexpr std::size_t size() const;       (4)
constexpr bool empty() const;             (5)

1	Returns the number of rows in the bit-matrix.
2	Returns the number of columns in the bit-matrix.
3	Returns `true` if the bit-matrix is square i.e. if `rows() == cols()`.
4	Returns the number of elements in the bit-matrix.
5	Returns `true` if the bit-matrix has no elements (so `size() == 0`), returns `false` otherwise.

Example

#include <GF2/GF2.h>
int main()
{
    GF2::Matrix<> m(3, 4);
    std::cout << "m.rows():      " << m.rows()      << '\n';
    std::cout << "m.cols():      " << m.cols()      << '\n';
    std::cout << "m.size():      " << m.size()      << '\n';
    std::cout << "m.is_square(): " << (m.is_square() ? "YES" : "NO") << '\n';
    std::cout << "m.empty():     " << (m.empty()     ? "YES" : "NO") << '\n';
}

Output

m.rows():      3
m.cols():      4
m.size():      12
m.is_square(): NO
m.empty():     NO
