bool ph::math::TMatrix2< T >::solve ( const std::array< std::array< T, 2 >, N > & bs, std::array< std::array< T, 2 >, N > * out_xs ) const

inline

Solve N linear systems of the form Ax = b.

Treating this matrix as A, linear systems A*x_i = b_i (0 <= i < N) are solved. This is equivalent to having bs as a 2 by N matrix and passing them in column-major (out_xs follows similarly, except it's for outputs).

Parameters

	A	A 2x2 matrix.
	bs	N 2x1 vectors (or a 2xN matrix in column-major).
[out]	out_xs	N 2x1 vectors (or a 2xN matrix in column-major).

Returns

If x is successfully solved, method returns true and out_xs stores the answer; otherwise, false is returned and what out_xs stores is undefined.

solve() [2/3]

template<typename T >

bool ph::math::TMatrix2< T >::solve ( const std::array< T, 2 > & b, std::array< T, 2 > * out_x ) const

inline

Solves linear systems of the form Ax = b.

Treating this matrix as A.

Parameters

	b	A 2x1 vector.
[out]	out_x	A 2x1 vector.

Returns

If x is successfully solved, method returns true and out_x stores the answer; otherwise, false is returned and what out_x stores is undefined.

solve() [3/3]

template<typename T >

bool ph::math::TMatrix2< T >::solve ( const TVector2< T > & b, TVector2< T > * out_x ) const

inline

Solves linear systems of the form Ax = b.

See solve(const std::array<T, 2>&, std::array<T, 2>*) for details.
