FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package science

science

PHP library for extended mathematical operations. Its mostly focused on operations with Complex numbers, Quaternions and Linear Algebra.

Key features and advantages

Improved Math::pow($base, $exponent) function, able to raise any real or complex number to any real or complex exponent
Support for SymPy )
Physics units conversion (more units to be added...) using (new Quantity(0.7, IAU::parsec))->convert(SI::metre)

Installation

Library is available on Packagist and could be installed using CLI command:

Usage

If installed via composer include composer generated autoloader and add use irrevion\science\Math\Math statement for example.
If you are not using composer or using a custom folder you can modify and include custom autoloader.
Example:

Examples

Scalar is a basic number class:

Basic arithmetic operations available:

As mentioned above, significant enhancement of pow() function has been made:

It is also possible to get all roots of a number

So, as you can see, the following operations are supported:

raise of real number to a real power
raise of real number to a fractional power (2/3 means cubic root squared)
raise of negative number to a rational or real power (1/n is n-th root of a number)
raise of an any number to negative power (rational or real)
raise of a number to imaginary or complex power
raise of an any available value (entity-type instance: mixed/numeric, Scalar, Fraction, Imaginary, Complex, ComplexPolar, QuaternionComponent, Quaternion, Vector, etc) at least to positive integer power
