anonymous enum

Enumerator
RowsAtCompileTime	The number of rows at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See Also MatrixBase::rows(), MatrixBase::cols(), ColsAtCompileTime, SizeAtCompileTime
ColsAtCompileTime	The number of columns at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See Also MatrixBase::rows(), MatrixBase::cols(), RowsAtCompileTime, SizeAtCompileTime
SizeAtCompileTime	This is equal to the number of coefficients, i.e. the number of rows times the number of columns, or to Dynamic if this is not known at compile-time. See Also RowsAtCompileTime, ColsAtCompileTime
IsVectorAtCompileTime	This is set to true if either the number of rows or the number of columns is known at compile-time to be equal to 1. Indeed, in that case, we are dealing with a column-vector (if there is only one column) or with a row-vector (if there is only one row).
Flags	This stores expression flags flags which may or may not be inherited by new expressions constructed from this one. See the list of flags.
CoeffReadCost	This is a rough measure of how expensive it is to read one coefficient from this expression.

Member Function Documentation

Index cols ( ) const

inline

Returns: the number of columns.

See Also: rows(), ColsAtCompileTime

Referenced by SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::innerSize(), SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::outerSize(), and SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::size().

const internal::eval<Derived, IsSkyline>::type eval ( ) const

inline

Returns: the matrix or vector obtained by evaluating this expression.

Notice that in the case of a plain matrix or vector (not an expression) this function just returns a const reference, in order to avoid a useless copy.

Index innerSize ( ) const

inline

Returns: the size of the inner dimension according to the storage order, i.e., the number of rows for a columns major matrix, and the number of cols otherwise

Index nonZeros ( ) const

inline

Returns: the number of nonzero coefficients which is in practice the number of stored coefficients.

Index outerSize ( ) const

inline

Returns: the size of the storage major dimension, i.e., the number of columns for a columns major matrix, and the number of rows otherwise

Index rows ( ) const

inline

Returns: the number of rows.

See Also: cols(), RowsAtCompileTime

Referenced by SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::innerSize(), SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::outerSize(), and SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >::size().

Index size ( ) const

inline

Returns: the number of coefficients, which is rows()*cols().

See Also: rows(), cols(), SizeAtCompileTime.
