| TutorialAdvancedInitialization.dox | 13 Eigen offers a comma initializer syntax which allows the user to easily set all the coefficients of a matrix,
14 vector or array. Simply list the coefficients, starting at the top-left corner and moving from left to right
16 or too many coefficients, Eigen will complain.
67 used to initialize all coefficients to zero. There are three variants. The first variant takes no arguments
82 Similarly, the static method \link DenseBase::Constant() Constant\endlink(value) sets all coefficients to \c value.
85 \endlink fills the matrix or array with random coefficients. The identity matrix can be obtained by calling
89 one-dimensional arrays; it yields a vector of the specified size whose coefficients are equally spaced between
140 The expression <tt>m + MatrixXf::Constant(3,3,1.2)</tt> constructs the 3-by-3 matrix expression with all its coefficients
