Cleve Moler has died

I only met him twice, so I don't have much to say, but let me share Alan's message instead, since he knew him well: https://discourse.julialang.org/t/cleve-moler-rip/137235.

I was honored to have worked with Cleve at Ardent Computer. He ran the benchmark and demo group squeezing performance out of thin air.

Great mathematician and a wonderful human being. I never stopped learning when I was around him. thttps://blogs.mathworks.com/cleve/2013/11/25/the-ardent-tita...

Cleve Moler was one of the big names in numerical methods, and participated in creation of canonical FORTRAN libraries for solving linear equations, and matrix algorithms more generally.

To teach this more conveniently to his students, he wrote the original version of MATrixLABoratory to allow interactive exploration of the library functions without having to compile FORTRAN code. The original version was about 2000 lines of code in FORTRAN.

Engineering students loved it so much that he decided to make a company around this product. His buddy expanded and rewrote the interpreter in C, for a PC, and the rest is history:

"In 1983 Jack Little suggested the creation of a commercial product based on MATLAB. I said I thought that was a good idea, but I didn't join him initially. The IBM PC had been introduced only two years earlier and was barely powerful enough to run something like MATLAB, but Little anticipated its evolution. He left his job, bought a Compaq PC clone at Sears, moved into the hills behind Stanford, and, with my encouragement, spent a year and a half creating a new and extended version of MATLAB written in C. A friend, Steve Bangert, joined the project and worked on the new MATLAB in his spare time."

Amazing impact that person had. Although MATLAB probably kind of outdated these days as anything can be accomplished in Julia and Py and I remember deploying that software being deliberately made difficult by this being shareware. When I studied almost everybody ended up using MATLAB during their study and almost everybody ended up hating it when it came to publishing results and doing demonstrations.
