static auto MayaFlux::Yantra::OperationHelper::extract_native_data ( const EigenMatrix &  matrix ) -> std::vector<std::span<const typename EigenMatrix::Scalar>>

inlinestatic

Extract native-typed column spans from any Eigen matrix.

Returns one span per column in T::Scalar, aliasing the matrix's own storage via Eigen::Map. The matrix must outlive the returned spans.

Template Parameters

EigenMatrix

Any Eigen matrix type. T::Scalar is the native type.

Parameters

matrix

Source matrix.

Returns

Per-column spans in T::Scalar.
