Constructor & Destructor Documentation

virtual LSSolver::~LSSolver ( )

inlinevirtual

Destructor.

Note

The data members m_vA and m_vb will point to some memory outside this class , as a result no memory should be deleted in this destructor

Member Function Documentation

virtual int LSSolver::solve ( double *  result, double *  b  )

pure virtual

Solves the least squares problem Ax = b.

A is a mxn matrix, b is a mx1 vector, and x is the solution which is a nx1 vector.

Parameters

[out]	result	The x in Ax = b, which is a nx1 vector
[in]	b	The right-hand-size, which is a mx1 vector

Returns

0 if success; otherwise if failure

Warning

The input array b may be modified in this method

Implemented in QRSolver.
