This should be easy to fix with a new "Participant" API which stores it's own heap-allocated Participant instance. ```fortran type :: participant private type(c_ptr) :: ptr = c_null_ptr ! Participant...

Based on this issue reported at Discourse (https://fortran-lang.discourse.group/t/curious-problem-with-cmake-related-to-the-feq-parse-project/6915), it looks like Fortran include files also have the same problem. An example would be ```fortran ! main.f90 call hello() contains include...

It appears like the tools to unbundle device code introduced in https://github.com/compiler-explorer/compiler-explorer/pull/4019, don't work anymore for newer versions of icx/ifx including 2023 and 2024.

I've added #486 which is also relevant. I would be keen to have the SciPy `.npz` format supported, which is also used to pass sparse matrices.

> the TACO library also offers an API of the sorts for C++ and Python: http://tensor-compiler.org/docs/scientific_computing.html The formats supported by TACO are: * [Matrix Market (Coordinate) Format (.mtx)](http://math.nist.gov/MatrixMarket/formats.html#MMformat) * [Rutherford-Boeing...

There is also a naive text format that MATLAB uses, described under - [spconvert](https://www.mathworks.com/help/matlab/ref/spconvert.html) - [Importing Sparse Matrices](https://www.mathworks.com/help/matlab/math/constructing-sparse-matrices.html#f6-34158) I've used it in the past, to quickly output a matrix and...

Can we use the MatrixMarket routines from NIST (potentially, wrapped in a nicer interface)? Or should we do a clean-room design and implementation?

A full Python interface for MINPACK is available since one year now: https://github.com/fortran-lang/minpack/tree/main/python A few tests serving as examples can be found here: https://github.com/fortran-lang/minpack/blob/main/python/minpack/test_library.py But I guess this doesn't really...

I recall reading (perhaps in the MINPACK User Guide) that double precision is practically a must for difficult optimization problems. How is it with other popular CSE languages like MATLAB,...

Does [generic selection](https://en.cppreference.com/w/c/language/generic) (C11) work in C++ mode too? I couldn't find an answer so I assume it's _no_. In C++ we would need to use function overloading or template...
