/// \returns an expression of \c *this with reshaped sizes.
///
/// \param nRows the number of rows in the reshaped expression, specified at either run-time or compile-time, or AutoSize
/// \param nCols the number of columns in the reshaped expression, specified at either run-time or compile-time, or AutoSize
/// \tparam Order specifies whether the coefficients should be processed in column-major-order (ColMajor), in row-major-order (RowMajor),
///               or follows the \em natural order of the nested expression (AutoOrder). The default is ColMajor.
/// \tparam NRowsType the type of the value handling the number of rows, typically Index.
/// \tparam NColsType the type of the value handling the number of columns, typically Index.
///
/// Dynamic size example: \include MatrixBase_reshaped_int_int.cpp
/// Output: \verbinclude MatrixBase_reshaped_int_int.out
///
/// The number of rows \a nRows and columns \a nCols can also be specified at compile-time by passing Eigen::fix<N>,
/// or Eigen::fix<N>(n) as arguments. In the later case, \c n plays the role of a runtime fallback value in case \c N equals Eigen::Dynamic.
/// Here is an example with a fixed number of rows and columns:
/// \include MatrixBase_reshaped_fixed.cpp
/// Output: \verbinclude MatrixBase_reshaped_fixed.out
///
/// Finally, one of the sizes parameter can be automatically deduced from the other one by passing AutoSize as in the following example:
/// \include MatrixBase_reshaped_auto.cpp
/// Output: \verbinclude MatrixBase_reshaped_auto.out
/// AutoSize does preserve compile-time sizes when possible, i.e., when the sizes of the input are known at compile time \b and
/// that the other size is passed at compile-time using Eigen::fix<N> as above.
///
/// \sa class Reshaped, fix, fix<N>(int)

/// - If `Order==ColMajor` (the default), then it returns a column-vector from the stacked columns of \c *this.

/// \include MatrixBase_reshaped_to_vector.cpp
