Detailed Description
template<class E, class F>
class shark::blas::matrix_unary< E, F >
class which allows for matrix transformations
transforms a matrix expression e of type E using a Functiof f of type F as an elementwise transformation f(e(i,j)) This transformation needs to leave f constant, meaning that applying f(x), f(y), f(z) yields the same results independent of the order of application. Also F must provide a type F::result_type indicating the result type of the functor. F must further provide a boolean flag F::zero_identity which indicates that f(0) = 0. This is needed for correct usage with sparse arguments - if f(0) != 0 this expression will be dense! todo: desification is not implemented
