Hadamard (1865-1963) was one of more important mathematicians at the turn of 19th century. He is most celebrated for his contributions in analytical functions and mathematical physics. His most important result is the prime number theorem, which he proved in 1896 (at the same time as C. J. De La Vallée-Poussin). In this article we introduce Hadamard matrices, their characterizations with Hadamard graphs, geometries and Hadamard codes, some interesting constructions and applications of Hadamard matrices in practiceJ. Hadamard (1865-1963) je bil eden izmed pomembnejših matematikov na prehodu iz 19. v 20. stoletje. Njegova najpomembnejša dela zajemajo področja teorije analitičnih funkcij in matematične fizike. Najbolj znan pa je po dokazu izreka o gostoti praštevil (leta 1896, hkrati s C. J. De La Vallée-Poussinom). V članku predstavljamo Hadamardove matrike, njihove karakterizacije s Hadamardovimi grafi, geometrijami in Hadamardovimi kodami ter nekaj zanimivih konstrukcij in uporabo Hadamardovih matrik v praksiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo matematikov, fizikov in astronomov
