Although it works as well as ever, as of 2024, Blitz++ is thoroughly obsolete, which results in a number of annoyances when using it in modern C++ code.\n\nIn the meantime, Fortran-90 / NumPy style arrays have received high-level thought in the C++ Standards community, resulting in `std::mdspan`.  I highly recommend anyone starting a new project to consider this alternative before using Blitz++.  MDSpan is part of C++23 and in theory should be supported by popular compilers \"out of the box.\"  If your C++ compiler does not (yet) support MDSpan, I would try using the publicly available [Reference Implemenation](https://github.com/kokkos/mdspan).  Here is more information on MDSpan:\n\n* https://en.cppreference.com/w/cpp/container/mdspan\n* https://www.studyplan.dev/pro-cpp/mdspan\n* https://www.osti.gov/servlets/purl/1646434\n\nBlitz++ has not received new features for many years, and will not going forward either.  However, it is likely to be required for many years by a number of existing projects, and is provided here for users and developers of those projects.\n\n# Overview\n\nBlitz++ is a C++ template class library that provides high-performance multidimensional array containers\nfor scientific computing. \n\nBlitz++ has gone through some changes in location:\n\n 1. The original Blitz++ website was located at ``http://oonumerics.org/blitz`` \n    (archived at http://www.math.unipd.it/~michela/OP.htm).  \n\n 2. Blitz++ then moved to SourceForge, at http://www.sourceforge.net/projects/blitz.\n\n 3. The latest maintained version of Blitz++",
