Clifford Multivector Toolbox
A toolbox for computing with Clifford algebras in MATLAB
...The toolbox is designed to work in the same way as MATLAB's own functions by overloading standard MATLAB functions with Clifford multivector versions. The toolbox can compute with any Clifford algebra with signature (p,q,r) but only with one algebra at a time. From version 2 of the toolbox onwards, computation is also supported with conformal geometric algebras (CGA), based on an underlying Clifford algebra to provide the numerical computation. The additional functionality does not impact on the original Clifford algebra functions of the toolbox. There is a (low traffic) mailing list for release announcements etc. ... -

polynomial-roots-calculation
Application for calculating the real roots of a polynomial
..., that make the needed precision increase, making the computational complexity for high-degree polinomials poor. But I have been able to make it work with a 40-degree polynomial, with two very proximal zeroes arround x=1000. It needs a precision of arround 60 digits. The problem comes with very-high degree polynomials. The higher is the degree, the faster the execution time increases. But for common examples, the application does the job well.

Fantasy Land Specification
Specification for interoperability of JavaScript algebraic structures
..."Value" is any JavaScript value, including any which have the structures defined below. "Equivalent" is an appropriate definition of equivalence for the given value. The definition should ensure that the two values can be safely swapped out in a program that respects abstractions. For example, two lists are equivalent if they are equivalent at all indices, two plain old JavaScript objects, interpreted as dictionaries, are equivalent when they are equivalent for all keys, two promises are equivalent when they yield equivalent values, etc. -
