The basic data structure in SciPy is a multidimensional array provided by the NumPy module.

Older versions of SciPy used Numeric as an array type, which is now deprecated in favor of the newer NumPy array code.

For example, in the MATLAB or NumPy function < tt > pinv </ tt >, the tolerance is taken to be, where ε is the machine epsilon.

NumPy is open source and has many contributors.

In comparison, MATLAB boasts a large number of additional toolboxes, notably Simulink ; whereas NumPy is intrinsically integrated with Python, a more modern, complete, and open source programming language.

The following is a simple example of how to do interactive array manipulations and plot a graph with NumPy and Matplotlib.

NumPy is based on two earlier Python array packages.

NumPy is a merge between the two that builds on the code base of Numeric and adds the features of Numarray.

While the source code is freely available and it contains significant documentation, there is also an extensive official Guide to NumPy.

The release version 1. 5. 1 of NumPy is compatible with Python versions 2. 4 – 2. 7 and 3. 1 – 3. 2.

Conversely, CPython applications that depend on extensions to the language that are implemented in C ( e. g. NumPy ) are not compatible with IronPython, although a commercially-supported open source project to address this is underway.

The noncentral F-distribution is implemented in the R language ( e. g., pf function ), in MATLAB ( ncfcdf, ncfinv, ncfpdf, ncfrnd and ncfstat functions in the statistics toolbox ) in Mathematica ( NoncentralFRatioDistribution function ), in NumPy ( random. noncentral_f ), and in Boost C ++ Libraries.

* Gensim is a Python + NumPy framework for Vector Space modelling.

Libraries like NumPy, SciPy and Matplotlib allow Python to be used effectively in scientific computing.

Using NumPy in Python gives functionality comparable to MATLAB since they are both interpreted, and they both allow the user to write fast programs as long as most operations work on arrays or matrices instead of scalars.

* SciPy-a scientific data analysis system for Python, based on the NumPy classes

Common numerical programming environments such as MATLAB, SciLab, NumPy and the R language provide some of the simpler feature extraction techniques ( e. g. principal component analysis ) via built-in commands.

In this respect, PDL follows in the footsteps of the APL programming language, and it has been compared to commercial languages such as MATLAB and Interactive Data Language, and to other free languages such as NumPy and Octave.

Many standard data analysis software systems are often used for feature selection, such as SciLab, NumPy and the R language.

Internally, both MATLAB and NumPy rely on LAPACK for efficient linear algebra computations.

The ancestor of NumPy, Numeric, was originally created by Jim Hugunin with contributions from several other developers.

In 2005, Travis Oliphant created NumPy by incorporating features of Numarray into NumPy with extensive modifications.

These languages, of which APL, IDL, NumPy, PDL, and S-Lang are examples, allow the programmer to manipulate complete film clips and other data en masse with simple expressions derived from linear algebra and vector mathematics.

2009 SciPy meeting had several sessions on SciPy and NumPy.

* Matplotlib, a plotting package based on NumPy

To avoid installing a whole package just to get an array object, this new package was separated and called NumPy.

The American-Negro Suite is in a sense an extension of the Cotton Club songs in that it is a collection of Negro songs, not for a night club, but for the concert stage.

You should make any request for an extension early so that if it is refused, your return may still be on time.

An extension of 2 months beyond the regular due date for filing is also available to taxpayers making returns for a fiscal year.

Such interest must be paid even though an extension of time for filing is granted.

( To avoid any possible excuse for a dripping parade through your house, it is a good idea to have a telephone extension near the pool as well as a direct outdoor route between the pool, and the parking area.

The observational data determining the concentration distribution have a range of error which is magnified in the extension into the micrometeorite region.

The other misconception is that our ecumenical problems will be solved if only the knowledge of the church in its world-wide extension and its interdenominational connections, now comprehended by many national leaders, can be communicated to all congregations.

In general, friendly contact with a member followed by contact with a clergyman will account for a major share of recruitment by the churches, making it quite evident that the extension of economic integration through co-optation is the principal form of mission in the contemporary church ; ;

`` The important thing from now on '', he said, `` is not to mourn the past but to seize the future opportunity to prevent the loss in northern Viet Nam from leading to the extension of Communism throughout Southeast Asia ''.

The " tail " is only possessed by the male and is an extension of the cloaca and used to inseminate the female.

Basic theories, such as arithmetic, real analysis and complex analysis are often introduced non-axiomatically, but implicitly or explicitly there is generally an assumption that the axioms being used are the axioms of Zermelo – Fraenkel set theory with choice, abbreviated ZFC, or some very similar system of axiomatic set theory like Von Neumann – Bernays – Gödel set theory, a conservative extension of ZFC.

In the case of a Galois extension L / K the subgroup of all automorphisms of L fixing K pointwise is called the Galois group of the extension.

An extension of this is the sacred cockfight, ” a popular form of fertility worship among almost all Southeast Asians ” considered by some in the Judeo-Christian ethic as a form of ’ fertility worship ’ or Baalim.

The more humid regions have a richer vegetation ; dense forest where the rainfall is greatest and variations of temperature least, conditions found chiefly on the tropical coasts, and in the west African equatorial basin with its extension towards the upper Nile ; and savanna interspersed with trees on the greater part of the plateaus, passing as the desert regions are approached into a scrub vegetation consisting of thorny acacias, etc.

Also from there is the word bung, from the Sydney pidgin English ( and ultimately from the Sydney Aboriginal language ), meaning " dead ", with some extension to " broken " or " useless ".

In abstract algebra, a field extension L / K is called algebraic if every element of L is algebraic over K, i. e. if every element of L is a root of some non-zero polynomial with coefficients in K. Field extensions that are not algebraic, i. e. which contain transcendental elements, are called transcendental.

For example, the field extension R / Q, that is the field of real numbers as an extension of the field of rational numbers, is transcendental, while the field extensions C / R and Q (√ 2 )/ Q are algebraic, where C is the field of complex numbers.
