`bit::matrix` — Minimize the Space Used

Potentially change the capacity of a bit-matrix.

1constexpr bit::matrix &shrink_to_fit();

1: This is a request to minimize the unused/excess matrix::row_capacity and matrix::col_capacity . May do nothing.

The method returns *this, so you can chain it with other calls.

The method will not change the dimensions of a bit-matrix (so rows(), cols(), and size() remain unchanged). No elements are added or deleted.

If the capacity does change, all the old values are unaltered, but be aware that any pre-existing element references are invalidated.
