Explanation for the "MathPiper class" email.
|
| |
During the past 5 weeks, I taught a short MathPiper class to a small group of mathematics teachers who are part of an online mathematics email list. The previous email was the "final thoughts" email I sent to the class. Ted

MathPiper class final thoughts.
|
| |
The MathPiper class has officially ended. I learned quite a bit during the past five weeks and I hope at least some of you learned some new things too :-) Ever since I started the MathPiper project in 2008, I have been trying to figure out who to "market" MathPiper too when the time comes to officially release it. One possibility is to advertise MathPiper... more »

some minor improvements you may be interested in
|
| |
Hi, You may be interested in some new yacas developments like r2590 and 2592. The latter was even discussed in comments to issue 90. I'd have commited the patches myself, but I've no idea which is the current development branch. Grzesiek

multivariate polynomials and printing to output
|
| |
From time to time, users have complained (and I have complained, too) about the fact that MathPiper sometimes outputs multiple-term expressions in an order determined by rules not immediately apparent. Although a bit inconvenient at times, this causes no real harm, I believe. But when we come to working with multivariate polynomials, it may be... more »

some things recently noticed
|
| |
1. Minor matter. In the MathPiper IDE, if you open more than 10 windows, all windows after the ninth receive the number 0 and replace the previous one. Is that a bug, or intentional? 2. Middling matter. In MathPiper docs, I pick just about any scripted function, and scroll down to where it says "view source code". When I hit... more »

How Mathematica handles the "types" issue.
|
| |
I have been researching the "types" issue we have been discussing, and here is one way that Mathematica handles it: "You can easily create your own "types" of data in Mathematica. For example, if you want to create a type that represents an integer modulo n, you can just start using objects of the form ModularInteger[i, n,] The function... more »

progress on native module for polynomial factoring
|
| |
It's interesting how all kinds of different things in mathematics have a way of coming together. I have been working on factoring univariate polynomials using only mathpiper functions. The YACAS function BinaryFactors() can correctly find all the LINEAR polynomial factors, but leaves behind a residual polynomial which is... more »

removing jas dependency for Factoring polynomials
|
| |
I have begun the task of removing dependency on JAS from the polynomial factoring functions, and replacing it with "native" MathPiper code. I am working in a private directory until things become sufficiently stable, so nothing will show up in the repository for a while. Question: In going over the code which is needed for this job, I seem to... more »
