CodeCogs | Open Source Scientific Library (C/C++, .NET, Excel)

This website and our name "Code Cogs" embody three key ideas: Providing the core digital ingredients needed to build larger solutions, the digital "gears" you can find in our library. Providing digital software in the form and language you need, not the way we like to write it. Developing tools to simplify the creation and evaluation of mathematics, no matter how it is used. Overall, every part of CodeCogs is designed to reduce the complexity of digital software and make technical solutions accessible to as many people as possible. Science and engineering don't need to be complicated! We are gradually building a series of world-class tools that will connect to each other over time to form a powerful suite that we believe will greatly simplify the creation of digital software. Currently this includes: The world's leading online equation editor Provides an interactive interface to the acclaimed LaTeX markup language for producing great-looking equations. Now supports output in MATHML format, the main standard adopted by browsers and math applications - except that MATHML cannot be written freehand vertically. Allows equations to be embedded in other websites, forums or blogs, or even copied into most desktop applications. fx rendering Excel add-in that allows converting plain text formulas to formatted equations. Helps with documentation, debugging and testing of spreadsheets. And more legends... An Open Source Numerical Library A dynamic website where anyone can add code and license it under terms that suit them. Written in C/C++ for performance and quality. Export wrappers for Excel, Python, PHP, C#. A self-validating website with instant calculators that allow testing components directly through the website. Atomic code structure so users only download the code they need. A reference library with great solutions that help users learn by example. Our History - Motivation The website was started in 2004 to solve the problems we (its creators) had in finding a well-documented, easy to navigate, and affordable numerical C/C++ code library. In particular, we wanted high-quality software that could be used both in commercial environments (where it could be incorporated into proprietary software) and in open source software systems. Furthermore, we wanted an "automated" system that allowed users to submit code on their own terms and license (and download) other people's software as needed. This was in stark contrast to other numerical libraries. Having built the initial C/C++ codebase, we now wanted to make the library as accessible to as wide an audience as possible. To this end, we introduced the CodeCogs instant calculator, which allowed most components on the site to be used through the site itself. This not only allowed developers to test the underlying code, but for many users, they could do all the calculations they needed directly through the site. In 2007, we began to receive more and more requests from users who wanted to use our Equation Editor on their sites. This was a system we had developed to help us keep track of pages of numbers, but it was clear that it had wider appeal. We soon realized that we could allow anyone to use this system to create formulas for their sites, forums, and blogs. Today, the Equation Editor is used on over 15,000 sites, and we generate over 2 million formulas per day. Realizing the popularity of the Equation Editor, we turned our attention to Excel, another system that had mathematical formulas (or equations) at the core of its platform, but we felt there was no good way or easy way to view them in a natural form. This led to the birth of fx Render. We continued to innovate, but everything CodeCogs does involves mathematical equations, and our tools provide ways to visualize, manipulate, and evaluate them. In the coming year, you will see more innovations that increasingly tie our core products together and help engineers and scientists do more with less. We value your support and suggestions, so please feel free to contact us.
