Define data structures to contain the Jacobian element matrix.// Following basic finite element terminology we will denote these// "Ke". More detail is in example 3.DenseMatrix<Number> Ke;// This vector will hold the degree of freedom indices for// the element. These define where in the g...
由于rcppeigen版本3.3.3.0MappedSpareMatrixT一直是弃用。由于某种原因,当使用这种新类型汇编功能时,我会发现错误。 例如(基于这个问题); 编辑:提出了无涂层的建议 - 仍然遇到同样的错误。 #include<RcppEigen.h> typedefEigen::Map<Eigen::SparseMatrix<double> > mappedSparseMatrix; ...
I would like to use AMD AOCL sparse library in a C program. Specifically, I am using aocl library compiled using gcc. I can build and run the C++ examples in the amd-sparse folder of aocl. For example "sample_spmv.cpp" builds on my system using: g++ sample_spmv.cpp -o sample_...

So PARDISO is a looped program, one can use it multiple times - hence the term phase, interesting turn of phrase. I will do the switches, and set the b matrix. I knew I had not set the b, but I tried it each time I put in a variable to see what errors I kept getting. I ha...
