MongoDB Atlas runs apps anywhere
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Seems to be closely related to Cellular automaton, except this creates a complex pattern from a mathematical function you input. See website for examples/live applets. This program makes use of an old GPL version of the JEP equation parser.
Expr4J aims to provide a general purpose expression parser, which is also compatible with Microsoft Excel. It will provide an implementation of the built in functions in MS Excel as well as a calculation engine.
Ceme Evaluates Math Expressions. Ceme is a free mathexpressionparser library written in C# supporting various operators and functions. It also has the option of adding your own functions. A wrapper DLL is provided for non .NET applications.
Currently, this project consists of a pure javamathexpressionparser optimized for repeated evaluation. Development of an interactive 3D math visualization application based on this parser is planned for the future.
Everything you need to build production-ready agents and models. Access 200+ Google and third-party AI models and tools.
Gemini Enterprise Agent Platform is Google Cloud's comprehensive platform for developers to build, scale, govern, and optimize agents and models. Choose from Google's most advanced models and third-party models like Anthropic's Claude Model Family.
Annotation based lexer and parser generator suitable for processing wide range of languages, from small domain specific languages to big ones like Java. Actions may be written directly as annotated java methods. Examples of expression language and Java5.
CurveDraw is a software that aim to draw 2D curves (Cartesian,polaire).
The software is 100% Java.CurveDraw is based on JEP library (JavaMathExpressionParser) .
JFEP is a Java fast mathematical expressionparser and evaluator. It is designed to avoid inefficiency and to support multiple evaluations without overhead.
Linear time, dynamic API for lexical analysis and parser generation. Allows for a text-based specification of formal languages with the well-known regular-expressions approach, and using Parsing Expression Grammars as the underlying engine.
Expression4J (MathExpressionParser) is a java framework used to manage mathematic expression stored in String object like "f(x,b)=2*x-cos(b)" or "g(x,y)=f(y,x)*-2". Expression gramar can be define by user (add new operator or type ...)
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
Parser for mathematical expressions written in Java. Expressions may contain variables, functions and constants. The parser turns a string argument into an expression tree, which then can be evaluated.
JEPLite is a light-weighted (re)implementation of the JavaExpressionParser (jep.sourceforge.net). The intention is to strip some of its not-so-often-used features, and thus speeding the rest. Includes expression optimizer.
Impression is the flexible and extensible parser of mathematical expressions written in Java. It supports user defined
operators, single or multi parameter functions and unlimited number
of parameters. It is designed to use with numerical methods.
JMAT : Java MATrix tools package.
Provides an easy-to-use class of matrix with MATLAB-like functions and syntax. JMAT also includes plots and histograms in 2D or 3D, an expressionparser, and some statistic simulation tools.
This is a mathexpressionparser/evaluator. It takes any string representing a mathexpression and returns the result of the evaluation of that expression. It supports variables/constants and user defined functions that can accept up to 2 parameters.
JAMATO : JAva MAtrix TOols package
Provides an easy-to-use class of matrix with MATLAB-like functions.
Jamato also includes Data Plots in 2D or 3D, Histograms in 2D or 3D, an expressionparser, and some basic statistic simulation tools.
XPath Parser is a library consisting of parser for XPath-expressions and a set of classes which are used to represent their structure. Parser creates class-based structure of an XPath expression which may be manipulated as required.
This small library ma
This library provides expression parsing functionality to Java applications, and includes support for all standard mathematical constants and functions, as well as providing functionality for user defined variables and functions.
