Eigen::Concat< Direction, LhsType, RhsType > Class Template Reference

#include <Eigen/src/Core/ConcatOp.h>

Detailed Description

template<int Direction, typename LhsType, typename RhsType>
class Eigen::Concat< Direction, LhsType, RhsType >

Expression of the concatenation of two dense expressions.

Template Parameters

Direction	either Vertical or Horizontal
LhsType	the type of the left-hand side expression
RhsType	the type of the right-hand side expression

This class represents an expression of the concatenation of two dense expressions, either vertically (stacking rows) or horizontally (stacking columns).

It is the return type of hcat() and vcat() and typically this is the only way it is used.

hcat()

template<typename Lhs, typename Rhs>

const Concat< Horizontal, Lhs, Rhs > hcat ( const DenseBase< Lhs > & lhs, const DenseBase< Rhs > & rhs )

related

Returns

an expression of lhs and rhs concatenated horizontally (side by side).

Both arguments must have the same number of rows. To concatenate more than two expressions, chain calls: hcat(hcat(a, b), c).

Example:

Matrix2d A, B;
auto C = hcat(A, B);  // C is 2x4

vcat()

template<typename Lhs, typename Rhs>

const Concat< Vertical, Lhs, Rhs > vcat ( const DenseBase< Lhs > & lhs, const DenseBase< Rhs > & rhs )

related

Returns

an expression of lhs and rhs concatenated vertically (stacked on top of each other).

Both arguments must have the same number of columns. To concatenate more than two expressions, chain calls: vcat(vcat(a, b), c).

Example:

Matrix2d A, B;
auto C = vcat(A, B);  // C is 4x2
