Julia shows that one can have machine performance without sacrificing human convenience. Abstractions in mathematics are captured as code through another technique from computer science, generic programming.
Abstraction, what good computation is really about, recognizes what remains the same after differences are stripped away. Multiple dispatch, a technique from computer science, picks the right algorithm for the right circumstance. Specialization allows for custom treatment. We introduce the Julia programming language and its design - a dance between specialization and abstraction. There are parts of a system for the programmer, and other parts best left untouched as they are built by the experts. One must prototype in one language and then rewrite in another language for speed or deploy- ment, andģ. High-level dynamic programs have to be slow,Ģ. Julia questions notions generally held as “laws of nature” by practitioners of numerical computing:ġ. \util.Bridging cultures that have often been distant, Julia combines expertise from the diverse fields of computer science and computational science to create a new approach to numerical computing. _pycall!(::P圜all.PyObject, ::P圜all.PyObject, ::Tuple) at C:\Users\azevelev\Dropbox\COMPUTATION\_QE_Moll\ML\Stanford\houseplots.jl:80 _pycall! at C:\Users\azevelev\.julia\packages\P圜all\zqDXB\src\pyfncall.jl:42 #110 at C:\Users\azevelev\.julia\packages\P圜all\zqDXB\src\pyfncall.jl:43
