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。

The header file in /inst/include/sparse.h imports the classes for the library and can be included in other projects using Rcpp in R. The R functionsparse_chol()provides an R interface using compressed column form as per theCsparseMatrixin the Matrix package. ...
To my knowledge this is not explicitly mentioned in the manual. Therefore changing values in the original array directly (NOT via the update function) will affect related operation results (e.g. matrix multiplication). This holds for "mkl_sparse_sp2" and "mkl_sparse_?_mm". ...
for this matrix, i am certain the smallest eigenvector will always be zero with the unit eigenvector. with dfeast_scsrev, i have the ability to encode this knowledge into the solver by setting the last ~250k values of the output array to 1, (250k-dimensiona...
