<p class="MsoNormal"><span style="font-size:12.0pt"> ve fyzikální laboratoři zpracováváme poměrně velké objemy dat. Ve scriptu MATLAB načítáme běžně 15-20 tisíc souborů s mnoha stovkami vzorků. Výsledkem je velká matice prostých číselných dat, např.
rozměru 100x19000. Matici ukládáme příkazem SAVE v režimu ASCII a i když to trvá někdy až 2 minuty, soubor se uloží. Problémem je jeho opětovné načtení, při kterém MATLAB zamrzne a často způsobí problém i Windows 7 Enterprise (používáme MATLAB R2016a 64bit).
Zkusili jsme načítání ruční i pomocí systému „Import Data“.<o:p></o:p></span></p>
