与模板的 triangularView 关联的特征错误
Eigen error associated with triangularView of template
我有以下函数抛出错误。我可以将问题隔离到行
A.template triangularView<Lower>().solveInPlace(MatrixXd::Identity(p,p)); // the problem line
但我无法弄清楚问题是什么以及如何解决它。
template <typename T, typename RNG>
inline void rInvWishRevCholesky_thread_inplace(Eigen::MatrixBase<T>& A,
const int v,
const Eigen::Ref<const Eigen::MatrixXd>& Psi,
RNG& rng){
int p = Psi.rows();
MatrixXd PsiInv = Psi.llt().solve(MatrixXd::Identity(p,p));
if (v <= p-1)
Rcpp::stop("v must be > Psi.rows - 1");
VectorXd z(p*(p-1)/2);
fillUnitNormal_thread(z, rng);
MatrixXd X = MatrixXd::Zero(p, p);
for (int i=0; i<p; i++){
boost::random::chi_squared_distribution<> rchisq(v-i);
X(i,i) = sqrt(rchisq(rng));
}
int pos = 0;
for (int i=1; i<p; i++){
for (int j=0; j<i; j++){
X(i,j) = z(pos);
pos++;
}
}
A.template noalias() = PsiInv.llt().matrixL()*X;
A.template triangularView<Lower>().solveInPlace(MatrixXd::Identity(p,p)); // the problem line
A.template transposeInPlace();
}
错误信息如下：

如有任何建议，我们将不胜感激！
solveInPlace 要求它的参数是可写的，MatrixXd::Identity(p,p) 是一个只读表达式。 （您希望从哪里获得该函数的结果？）
也许你想要的是这个？
A.noalias() = (PsiInv.llt().matrixL()*X).transpose()
.template triangularView<Upper>().solve(MatrixXd::Identity(p,p));
我有以下函数抛出错误。我可以将问题隔离到行
A.template triangularView<Lower>().solveInPlace(MatrixXd::Identity(p,p)); // the problem line
但我无法弄清楚问题是什么以及如何解决它。
template <typename T, typename RNG>
inline void rInvWishRevCholesky_thread_inplace(Eigen::MatrixBase<T>& A,
const int v,
const Eigen::Ref<const Eigen::MatrixXd>& Psi,

如有任何建议，我们将不胜感激！
solveInPlace 要求它的参数是可写的，MatrixXd::Identity(p,p) 是一个只读表达式。 （您希望从哪里获得该函数的结果？）
也许你想要的是这个？
A.noalias() = (PsiInv.llt().matrixL()*X).transpose()
.template triangularView<Upper>().solve(MatrixXd::Identity(p,p));
