Julia is a modern general purpose language. It was conceived to solve the two-language problem within scientific computing: algorithms are often developed in an expressive language such as Python or R, but have to be rewritten to Fortran or C to achieve desired performance. With Julia you only need one language, because Julia can walk like Python and run like C.
This three-day course is designed for developers with experience of other languages such as Python, R, Matlab, or Java and who want to get up to speed on Julia.
The course focuses on teaching good software engineering such as structuring your code into well organized small functions rather than writing large messy scripts. With knowledge of Julia you will be able to write high performance code for scientific computing, data science, and machine learning.

Finner du ikke det helt optimale kurset eller kombinasjonen av kurs? Da ordner vi det - sammen. Vi kan tilrettelegge kurs slik at de inneholder akkurat det dere har behov for. Vi kan sette opp et helt nytt kurs, eller tilpasse eksisterende kurs og materiell. Flere medarbeidere kan selvfølgelig også samles til et eget felles kurs, for maksimal effektivitet.
