## export plot driver in Standard...

I made the switch from classic to standard largely because the 2D plot drivers/codes were completely rewritten in standard, and allowed me to export much prettier plots. This was a painful decision, because I always found classic to be more intuitive and faster. I don't care much for mouses and menus, I want code I can run and rerun as often as I like without having to remember a sequence of wrist movements. So now that I write in standard much of my recent work cannot be read...

## comments should be up-vote-able and list...

I have remarked on this ever since the launch of the second incarnation of mapleprimes. And I recall others expressing similar feelings.

1. It should be possible to "vote" for comments in the same way as we can vote for "answers".

## Pushing dsolve to its limits...

Maple 15

And so with this provocative title, "pushing dsolve to its limits" I want to share some difficulties I've been having in doing just that. I'm looking at a dynamic system of 3 ODEs. The system has a continuum of stationary points along a line. For each point on the line, there exist a stable (center) manifold, also a line, such that the point may be approached from both directions. However, simulating the converging trajectory has proven difficult.

I have simulated as...

## random dots on an egg...

Maple

This is more of a blog entry, mostly a note to myself.

I wanted to generate a list of points on the surface of a deformed sphere. It turns out that Robert recently showed how to do that on a unit sphere.

Adapting his code is straightforward. So here is what I came up with. One proc generates the random points on the surface of the ellipsoid. Another proc generates...

## style=point versus linestyle=dot in plot...

A short remark. This would be a blog entry if those still existed.

I am comparing plot,options.

The style=point option has versatile options for symbols, their sizes, the number of points:

`  , 'style' = point  , 'numpoints' = 50   , 'symbol' = solidcircle  , 'symbolsize' = 8`
