'''Scientific programming language''' may refer to two related, yet distinct, concepts in computer programming. In a broad sense, it describes any programming language used extensively in [[computational science]] and [[computational mathematics]], such as C, C++, Python, and Java.<ref>{{cite web |url=https://www.pcmag.com/encyclopedia/term/scientific-language |title=Definition of scientific language |website=PC Magazine Encyclopedia |publisher=Ziff Davis |access-date=13 May 2021}}</ref> In a stricter sense, it designates languages that are designed and optimized for handling mathematical formulas and matrix operations, offering intrinsic support for these tasks.<ref>{{cite web |url=http://www.yourdictionary.com/scientific-language |title=scientific language - Definition of scientific language |website=YourDictionary |publisher=The Computer Language Company Inc |access-date=27 March 2014}}</ref>

==Overview==
In the broad sense, a scientific programming language is one that is applied to numerical modeling, simulation, data analysis, and visualization. Languages such as Python, through libraries like NumPy, SciPy, and Matplotlib, have become dominant in fields ranging from machine learning to high-performance computing.<ref>{{cite web |url=https://www.datacamp.com/blog/top-programming-languages-for-data-scientists-in-2022 |title=Top 12 Programming Languages for Data Scientists in 2025 |website=DataCamp |access-date=3 April 2025}}</ref> Conversely, the strict sense emphasizes languages that provide built‐in support for matrix arithmetic and symbolic computation. Examples include [[Fortran]], [[MATLAB]], [[Julia (programming language)|Julia]], [[GNU Octave|Octave]], and [[R (programming language)|R]]. These languages are characterized by syntax that closely mirrors mathematical notation, enabling concise expression of complex formulas and operations.

==Historical context and evolution==
Historically, languages like [[ALGOL]] and [[Fortran]] laid the groundwork for scientific computing by introducing high-level constructs that enabled efficient numerical computations. Over time, the advent of proprietary tools such as [[MATLAB]] and open-source alternatives like [[GNU Octave]] expanded accessibility. In recent years, modern languages like [[Julia (programming language)|Julia]] have emerged to combine high performance with an expressive syntax, while general-purpose languages such as Python have evolved through robust scientific libraries to address a wide range of computational problems.<ref>{{cite web |last1=Zachary |first1=Joseph |title=Introduction to Scientific Programming: Computational Problem Solving Using Maple and C |url=https://www.cs.utah.edu/~zachary/IntroSciProg.html |website=University of Utah |access-date=13 May 2021}}</ref>

==Key features==
Scientific programming languages, particularly in the strict sense, typically include:
* Native or intrinsic support for arrays, vectors, and matrices.
* Concise syntax for mathematical operations.
* Advanced libraries for numerical linear algebra, optimization, and statistical analysis.
* Facilities for both symbolic and numerical computation.
* Tools for visualization and data exploration.

==Comparative examples==
===Linear algebra===
Languages with built-in support for matrix operations allow users to work directly with mathematical constructs. For example, the following Julia code solves a system of linear equations:

<syntaxhighlight lang="julia">
A = rand(20, 20)  # A is a 20x20 matrix
b = rand(20)      # b is a 20-element vector
x = A \ b         # x is the solution to A*x = b
</syntaxhighlight>

In contrast, Python—although a general-purpose language—provides similar functionality via its libraries:

<syntaxhighlight lang="python">
import numpy as np
A = np.random.rand(20, 20)
b = np.random.rand(20)
x = np.linalg.solve(A, b)
</syntaxhighlight>

This comparison highlights how general-purpose languages extend their capabilities with specialized libraries, whereas strict scientific languages often incorporate such features directly.

===Mathematical optimization===
Scientific programming languages also facilitate optimization tasks with syntax that closely mirrors mathematical notation. The following Julia example finds the minimum of the polynomial:

{{center|<math>P(x,y) = x^2 - 3xy + 5y^2 - 7y + 3</math>}}

<syntaxhighlight lang="julia">
using Optim

P(x,y) = x^2 - 3x*y + 5y^2 - 7y + 3

z₀ = [0.0, 0.0]     # Starting point for the optimization algorithm

optimize(z -> P(z...), z₀, Newton(); autodiff = :forward)
</syntaxhighlight>

Python offers comparable optimization routines through libraries such as SciPy, where automatic differentiation and specialized algorithms are available, albeit not as an intrinsic language feature.

==Modern trends and emerging languages==
Recent trends in scientific computing emphasize both performance and ease of use. Modern languages like [[Julia (programming language)|Julia]] have been designed specifically to address these demands, combining the clarity of high-level syntax with the efficiency required for large-scale numerical computation.<ref>{{cite web |url=https://julialang.org/ |title=Julia Programming Language |website=JuliaLang.org |access-date=3 April 2025}}</ref> Additionally, emerging languages such as Nim are gaining attention due to their performance and available libraries for linear algebra, even though they rely on external libraries rather than built-in support. This nuanced landscape demonstrates that the term "scientific programming language" is evolving alongside computational needs and technological advances.
