Detailed Description

template<typename Scalar>
class Eigen::MatrixMarketIterator< Scalar >

Iterator to browse matrices from a specified folder.

This is used to load all the matrices from a folder. The matrices should be in Matrix Market format It is assumed that the matrices are named as matname.mtx and matname_SPD.mtx if the matrix is Symmetric and positive definite (or Hermitian) The right hand side vectors are loaded as well, if they exist. They should be named as matname_b.mtx. Note that the right hand side for a SPD matrix is named as matname_SPD_b.mtx

Sometimes a reference solution is available. In this case, it should be named as matname_x.mtx
