Julia Data Structures The following are some of the most common data structures we end up using when performing data analysis on Julia: Vector(Array) – A vector is a 1-Dimensional array. A vector can be created by simply writing numbers separated by a comma in square brackets. If you add a semicolon, it will change the row. Vectors are widely used in linear algebra. Note that in Julia the indexing starts from 1, so if you want to access the first element of an array you’ll do A[1]. Matrix – Another data structure that is widely used in linear algebra, it can be thought of as a multidimensional array. Here are some basic operations that can be performed in a matrix Dictionary – Dictionary is an unordered set of key: value pairs, with the requirement that the keys are unique (within one dictionary). You can create a dictionary using the Dict() function. Notice that “=>” operator is used to link key with their respective values. You a...
Comparing Julia and Python Python is the most popular language used widely by most of the developers. Whereas Julia is launched very recently in 2012 which is much younger than python. But many developers are likely to use Julia as it is catching on quickly, considering the rankings by red monk. Advantages of Julia From the beginning, Julia was designed for numerical and scientific computation. It's not surprising that Julia has numerous features for such instances of use: Faster by default. JIT compilation and JIT type declarations imply it can frequently beat “pure”, Python. With the means of external libraries, optimizations with tools such as Cython, third party JIT compilers python can be made faster, but Julia was designed to be faster right out from the gate. A mathematical friendly syntax. The users of computing languages and environments such as Matlab, R, Mathematica, and Octave are the targeted audience for Julia. Julia's syntax...
