Member Function Documentation

template<typename _Scalar , typename _Index >

_Index Eigen::internal::AmbiVector< _Scalar, _Index >::nonZeros

(

)

const

Returns

the number of non zeros in the current sub vector

Definition at line 125 of file AmbiVector.h.

{
  if (m_mode==IsSparse)
    return m_llSize;
  else
    return m_end - m_start;
}

template<typename _Scalar , typename _Index >

void Eigen::internal::AmbiVector< _Scalar, _Index >::restart

(

)

Must be called whenever we might perform a write access with an index smaller than the previous one.

Don't worry, this function is extremely cheap.

Definition at line 159 of file AmbiVector.h.

{
  m_llCurrent = m_llStart;
}

template<typename _Scalar , typename _Index >

void Eigen::internal::AmbiVector< _Scalar, _Index >::setBounds ( Index  start, Index  end  )

inline

Specifies a sub-vector to work on

Definition at line 42 of file AmbiVector.h.

{ m_start = start; m_end = end; }

template<typename _Scalar , typename _Index >

void Eigen::internal::AmbiVector< _Scalar, _Index >::setZero

(

)

Set all coefficients of current subvector to zero

Definition at line 166 of file AmbiVector.h.

{
  if (m_mode==IsDense)
  {
    for (Index i=m_start; i<m_end; ++i)
      m_buffer[i] = Scalar(0);
  }
  else
  {
    eigen_assert(m_mode==IsSparse);
    m_llSize = 0;
    m_llStart = -1;
  }
}
