Detailed Description

template<typename ExpressionType>
class Eigen::MatrixWrapper< ExpressionType >

Expression of an array as a mathematical vector or matrix.

This class is the return type of ArrayBase::matrix(), and most of the time this is the only way it is use.

MatrixBase::matrix(), class ArrayWrapper

Member Typedef Documentation

typedef Matrix<typename internal::traits<MatrixWrapper< ExpressionType > >::Scalar, internal::traits<MatrixWrapper< ExpressionType > >::RowsAtCompileTime, internal::traits<MatrixWrapper< ExpressionType > >::ColsAtCompileTime, AutoAlign | (internal::traits<MatrixWrapper< ExpressionType > >::Flags&RowMajorBit ? RowMajor : ColMajor), internal::traits<MatrixWrapper< ExpressionType > >::MaxRowsAtCompileTime, internal::traits<MatrixWrapper< ExpressionType > >::MaxColsAtCompileTime > PlainObject [inherited]

The plain matrix type corresponding to this expression.

This is not necessarily exactly the return type of eval(). In the case of plain matrices, the return type of eval() is a const reference to a matrix, not a matrix! It is however guaranteed that the return type of eval() is either PlainObject or const PlainObject&.

typedef Matrix<Scalar,EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime), EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime)> SquareMatrixType [inherited]

type of the equivalent square matrix

Member Function Documentation

ArrayWrapper<MatrixWrapper< ExpressionType > > array (  ) [inherited]
Returns:
an Array expression of this matrix
See also:
ArrayBase::matrix()

Definition at line 316 of file MatrixBase.h.

Index diagonalSize (  ) const [inherited]
Returns:
the size of the main diagonal, which is min(rows(),cols()).
See also:
rows(), cols(), SizeAtCompileTime.

Definition at line 101 of file MatrixBase.h.

MatrixWrapper< ExpressionType > & lazyAssign ( const Flagged< OtherDerived, 0, EvalBeforeAssigningBit > &  other ) [inherited]

Definition at line 477 of file MatrixBase.h.

bool operator!= ( const MatrixBase< OtherDerived > &  other ) const [inherited]
Returns:
true if at least one pair of coefficients of *this and other are not exactly equal to each other.
Warning:
When using floating point scalar values you probably should rather use a fuzzy comparison such as isApprox()
See also:
isApprox(), operator==

Definition at line 295 of file MatrixBase.h.

bool operator== ( const MatrixBase< OtherDerived > &  other ) const [inherited]
Returns:
true if each coefficients of *this and other are all exactly equal.
Warning:
When using floating point scalar values you probably should rather use a fuzzy comparison such as isApprox()
