coeff() [1/4]

template<typename T >

auto stan::math::var_value< T, internal::require_matrix_var_value< T > >::coeff ( Eigen::Index  i ) const

inline

View element of eigen matrices.

This creates a new vari_value<double> so unlike the other views this subset will not have the same adjoints as the original matrix and must be propogated back.

Parameters

i	Element to access
