December 1984
MATLAB debuts
MathWorks launched the first commercial MATLAB in December 1984 — an interactive tool for engineers to crunch matrices and plot results on a PCPersonal computer — a computer designed for individual use, especially desktop or laptop machines..
What it was for
MATLAB is built around matrices and vectors — engineers run simulations, plot data, and prototype control systems without writing low-level loops. Used in aerospace, automotive, finance, and academia. Simulink extends it for model-based design.
Why it's here
PCPersonal computer — a computer designed for individual use, especially desktop or laptop machines.-MATLAB turned Cleve Moler's matrix hobby into the dominant numerical computing environment for engineers.
Why it mattered
It proved interactive matrix math could ship on personal computers and sustain a commercial tools company.
What it solved
FortranFormula Translation — one of the first high-level languages, dominant in science and engineering.-era engineers needed fast matrix operations and plotting without recompiling for every experiment.
