Etymologically, the entry records: Named after Pierre-Simon, marquis de Laplace (1749 – 1827), a French scholar whose work was important to the development of mathematics, statistics, physics and astronomy. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Laplacian matrix, spelled L-A-P-L-A-C-I-A-N- -M-A-T-R-I-X, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
