Hello!

For me as well, and I have been into this calculator thing since 1976 or so. Yes, I have a "real" 15C and the "SE" and now the "CE", but, for example, the way compex matrices are dealt with is beyond my comprehension. Well, maybe I could work my through the manual and follow the examples, but if I then need to perform such a calculation three months later I would have to start from scratch again. It is amazing that they were able to put complex matrix algebra into such a tiny calculator, but by today's standards, the way it is done is totally counter-intuitive not even remotely close to how one would do it on a more modern machine. Or an older one with a FORTRAN compiler...

So unless one collects these things the value of their advanced functions (matrices, solver, intergrator, ...) is not really obvious in 2023. Or even in 1993.
