Version 1.0.0
-------------------------------------------------------------------------
CHANGES
* Versioned directly modulo very minor CRAN changes from 0.1.1 for CRAN
consistency.
Version 0.1.1
-------------------------------------------------------------------------
NEW FEATURES
* A new function called plug allows users to plug values into indeterminates in mpoly objects.
* mpoly now imports the polynom and orthopolynom packages, and has as.mpoly methods to parse their objects into mpoly objects.
* mpoly now imports reshape2 for some visualization stuff.
* A new function called chebyshev allows users to compute Chebyshev polynomials. This is based on orthopolynom.
* New functions called bernstein and bernsteinApprox allow users to compute Bernstein polynomials and approximate functions with Bernstein polynomials, see examples. A special as.function method exists for evaluating these in a numerically stable way.
* A new function called bezier allows users to compute the polynomials associated with Bezier curves. A special as.function method exists for evaluating these in a numerically stable way via de Casteljau's algorithm, based on a new function called bezierFunction (exported).
* Several new predicate functions are exported.
* ggplot2 is now imported.
CHANGES
* The internals of tuples have been changed, but the user shouldn't expect to see them.
FIXES
* A bug in mp functions where non-parenthetical exponents in parenthetical expressions were mis-parsed has been fixed.
* round.mpoly now drops terms rounded to have 0 coefficients.
* mpolyList now can be used inside functions and other environments (thanks @gitlongor)
Version 0.1.0
-------------------------------------------------------------------------
NEW FEATURES
* is.linear function.
* round now has a method applicable to mpoly objects that rounds the coefficients. this is particularly nice in combination with as.mpoly.lm.
* Hard braces are now allowed for variables, e.g. x[1,1]
CHANGES
* Vastly enhanced mp parser based on stringr 9.0.0 (now dependent on stringi).
* Tests added.
* Description file updated for CRAN's standards.
Version 0.0.5
-------------------------------------------------------------------------
NEW FEATURES
* Parenthetical expressions are now handled.
CHANGES
* Permutations now returns a better ordered listing of the permutations of a set. It also allows for the more flexible specification of (e.g.) permutations(5) for permutations(1:5).
FIXES
* Some negative parsing in mp has been fixed.
Version 0.0.4
-------------------------------------------------------------------------
CHANGES
* Division symbols in mp now return an error.
* mpoly now has a GPL-2 license.
FIXES
* Fixed a glitch in print.mpoly that made mp("-1 + y") print as "-1 1 + y".
* mpolyList now works on single elements, either a mpoly object (converting it to a mpolyList) or a call to mp.
* mp now properly handles constants raised to powers.
Version 0.0.3
-------------------------------------------------------------------------
FIXES
* Fixed an issue with as.mpoly (and is.mpoly.lm).
Version 0.0.2
-------------------------------------------------------------------------
NEW FEATURES
* as.mpoly method now defined for lm objects which makes an mpoly object out of a linear model.
Version 0.0.1
-------------------------------------------------------------------------
