I've created a new blog entry concerning what I think might be an idea worth consideration:     slide rule

Statistics:-ScatterPlot provides a mechanism to plot a lowess curve, and the implementation seems to be flexible and convenient. There is, though, a problem with using ScatterPlot. ScatterPlot only plots the curve. I would like to be able to do computations with the curve; for example, I would like to compute the sum of squared residuals. So I suggest that Statistics[DataSmoothing] include a separate procedure for generating a lowess curve (the same curve that ScatterPlot plots). Note: I have posted about using lowe

As a relatively new Maple user I've ran into the message that the linalg package is superceded by the LinearAlgebra Package many times in the help pages. However, after using many older titles that used relatively older versions of Maple to demonstrate applications, I've sometimes found many of the linalg packages very intuitive and user friendly in cases where the LinearAlgebra operation may have created a little confusion. This blog entry is just my plea to Maplesoft to...

In this example, look at E1. Is it E2 or E3? We cannot tell from the way Maple displays them. For the answer, keep reading. Shouldn't Maple put parentheses or something in its rendering of E2 at least?

> E1 := f @ log @@ 4;

> E2 := (f @ log) @@ 4;

Can someone help me with the Dagger command in the Physics package ? I can't seem to get it to work for matrices. thanks,

I'm running Maple 11 on a Windows XP machine. Should I bother getting the new update for Maple 11, or is this new release not applicable to me ? v/r,

The title says it all - although in the documentation of the Maple Toolbox for Matlab you can read that it is fully compatible with Matlab's Symbolic Math Toolbox, this is actually not the case. So better do not expect that after you install the Maple Toolbox you'll be able to use your old m-files that worked OK with Symbolic Math Toolbox - they might work, if they rely only on the most basic features. However, as soon as you need anything a little bit more complicated, you'll experience a lot of difficulties. One example for all - with Symbolic Math Toolbox you can have: >> var_str = '[a; b]' % symbolic matrix represented as char

I've been laying low for a while now, finding new ways to break and repair Maple. With Maple11, I've found at least two disturbing bugs. The first is in implicitplot(): Maple no longer allows for variable ranges that evaluate to numbers. In Maple10, the command plots[implicitplot](x^3=y-x, x=-5..5, y=0..x); plots correctly, whereas the same command in Maple11 results in the error message: "Error, (in plots/implicitplot) invalid input: invalid range for second variable" The second bug is yet another bug in Maple's eternally bug-ridden Worksheet package. I do not know if this bug exists in previous versions of Maple, but there is a problem reading in nested quotes. To see this bug, do the following:

To check the correctness of the result given by maple it would be nice to integrate a theory prover capability in maple or give more support to work them together.

Why isn't it still possible to easily create and play sound like with Mathematica?????

Does anyone know if Maple's handwriting recognition feature employ statistical pattern recognition in some way ? v/r,

I would like to see the ability to set the plot box and axes transparency, or even color of those items in some future release of Maple. Thanks, Tim

I recently installed maple11 and upgraded from maple10. However, I still have desktop icons for Maple10 and Maple10 classic mode. Does this mean that I now have the choice of using maple 10 or maple 11 on the same machine ? I thought that the automatic upgrade would have completely replaced any previous versions of maple found on one's machine ? Guidance welcomed, v/r,

Open a worksheet in document model, and input the next line in math model plot(x^2,x=-1..1,title="title"); and it will show a plot. Now select "title" in the quotation marks (not include quotation marks), type in "aabb" (not include quotation marks) and press enter, there will be an error. But if you select "title" including quotation marks, and change to "aabb" (including quotation marks), there will no problem.

Please use replies to this blog post for free-form wish list items for Maple 12. Anything you'd like to see, in any part of Maple, go for it.
