Re: [eigen] Problem extending MatrixBase

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]


I guess this is because of a recursive dependency. To make it work, in
the last two functions, replace:

const CwiseUnaryOp<ei_scalar_add_op<Scalar>, Derived>

by

const CwiseUnaryOp<ei_scalar_add_op<Scalar>, Derived>
