- 33 new snippets - unfuck doxygen output in Cwise (issues with function macros) - more see-also links from outside, making Cwise more discoverable * rename matrixNorm() to operatorNorm(). There are many matrix norms (the L2 is another one) but only one is called the operator norm. Risk of confusion with keyword operator is not too scary after all.

/** \class MatrixBase
|
|
*
|
|
* \brief Base class for all matrices, vectors, and expressions
|
|
*
|
|
* This class is the base that is inherited by all matrix, vector, and expression
|
|
* types. Most of the Eigen API is contained in this class. Other important classes for
|
|
* the Eigen API are Matrix, Cwise, and PartialRedux.
|
|
*
|
|
* Note that some methods are defined in the \ref Array module.
|
|
*
|
|
* \param Derived is the derived type, e.g. a matrix type, or an expression, etc.
|
|
*
|
|
* When writing a function taking Eigen objects as argument, if you want your function
|
|
* to take as argument any matrix, vector, or expression, just let it take a
|
|
* MatrixBase argument. As an example, here is a function printFirstRow which, given
|
|
* a matrix, vector, or expression \a x, prints the first row of \a x.
|
|
*
|
|
* \code
|
|
template<typename Derived>
|
|
void printFirstRow(const Eigen::MatrixBase<Derived>& x)
|
|
{
|
|
cout << x.row(0) << endl;
|
|
}
|
|
* \endcode
