[Axiom-developer] Manuel Bronstein

Manuel Bronstein died this week of a heart attack at age 42. Manuel leaves behind Karola (his wife) and six children. I just returned from a house-hunting trip in Pittsburgh to hear this terrible news. I worked with him at IBM Research and have maintained contact with him since that time. In fa

Changes http://page.axiom-developer.org/zope/mathaction/StatisticalFunctions/diff -- Martin, Your original statistics code above did not compile here on MathAction because MathAction requires that Axiom library code must beging with exactly:: )abbrev ... Typing ')abb' is not enough even thoug

[Axiom-developer] [statistical functions] Thank you!

[Axiom-developer] Rectangular and square matrix category definition

Hi, Do you know why there is no the shallowlyMutable attribute in rectangular and square matrix category (RMATCAT and SMATCAT respectively) ? In RectangularMatrixCategoryFunctions2, the map function contains new(m,n,0)$Matrix(R2) pretend M2 (M2 is approximatively RMATCAT) In other words, map ca

[Axiom-developer] [statistical functions] (nouveau)

Changes http://page.axiom-developer.org/zope/mathaction/StatisticalFunctions/diff -- I just started to hack together a couple of statistical functions. Should be extended of course. The median could be implemented in 'O(n)' steps, but I don't have the time. \begin{axiom} )abb package STAT Stati

Changes http://page.axiom-developer.org/zope/mathaction/RecurrenceRelationOperator/diff -- I just realised that this should be implemented rather as a domain, namely the domain of D-finite (or P-recursive) functions. They have quite a lot of structure: you can multiply them, add them, take the h
