IFileService should provide a method to see if a file exists

4

Having a `IFileService.FileExists(Uri uri, string fileName)` method would allow re-using the `IFileService` in the `DefaultDocumentRouter` (instead of passing a root dir and duplicating the path calculation). **EDIT**: The `DiskFileService` implementation...

Provide special TransposeMultiply operation for (Sparse)Matrix-Vector products

Since some iterative solvers may require an operation y

The `writeneighbors` method in [triangle.c](https://github.com/wo80/Triangle/blob/master/src/Triangle/triangle.c#L8011) (mis)uses the first subseg pointer of the triangle data structure for triangle numbering. This was not an issue for the original Triangle code, since the...

I've been working on Visual Studio compatibility lately (well, picked up work from a year ago), see https://github.com/wo80/essentia/ Here's what's in the fork: * CMake build script * RougeVector compatibility...

Github workflow: Segmentation fault

I was skipping over the _Checks_ tab of my recent pull request and in the _Tests_ section I saw a couple of `Segmentation fault (core dumped)`. This error is also...

I'm currently trying to use SuperLU in a C++ project and I'm getting the following error (Visual Studio): ``` slu_ddefs.h(270,12): error C2733: 'dgemv_': you cannot overload a function with 'extern...

This https://github.com/xiaoyeli/superlu/commit/90ee45dc836d8f4ff967cad4aa2821809b12fdc9#diff-862af30d14f5c76994c21cdb32acbba6da4cb1cd82f26144e417042f742608b2 completely defeats the purpose of https://github.com/xiaoyeli/superlu/pull/116 Please revert. It doesn't make any sense to have `#define complex singlecomplex` for "backward compatibility". There is no more use of `complex`...

Reducing memory allocations

5

I played around with the `ILinearSolver` interface of the `sparse-matrices` branch. Here's an implemetation which comes with zero additional memory allocations (using a custom [LU](https://github.com/wo80/mathnet-extensions/blob/master/src/Numerics/LinearAlgebra/Double/Factorization/ReusableLU.cs) implementation): ```c# class OptimizedLinearSolverForTesting :...

Delete USER frames

I'm trying to delete [USER](https://id3.org/id3v2.3.0#Terms_of_use_frame) frames from a bunch of mp3s using `id3 -2 -rUSER *.mp3`, but I cannot get this to work. The ID3 tag of a file looks...
