文件中有一个注释RcppEigenForward.h和RcppEigenWrap.h那是mappedSparseMatrix从欧吉3.30开始,将上游弃用。 如果我将其更改为 typedefEigen::SparseMatrix<double> mappedSparseMatrix; IE使用彻底的稀疏矩阵(与地图相对)然后进行编译。

What is the number of non-zeros elements in your input matrix and what is the size of this matrix?-Gennady I can assure you that my matrix is a sparse matrix, for the number of non-zero elements are 2% to 5% of total elements.However, I'm very surperised about what you said ...
