The Linear Algebra package seems only able to handle Vector and Matrix algebra when the dimensions are given specifically.

It would be very helpful if the package were to be extended to cope with the situation where some or all of the dimentions were given symbollically. Of course, assume could be used to indicate when two dimensions were equal.

Are there any plans in this direction for future releases of Maple?

An improvement which would make many applications involving Components a lot better would be if an "image" were a first-class object in Maple. That is to say, if an image object could be used in Components without having to refer to an external file.

It's a big weakness in Maple's functionality, that things like the following don't work.

bar:=ImageTools:-Create(...);

DocumentTools:-SetProperty(Label0,image,bar);

The above is just an...

Currently, using Explore results in a new worksheet which contains all the sliders and output components.

And there is code, which makes it all "work", that gets hidden in that new worksheet. But It's very awkward to copy those Components back to the original worksheet, because of the disassociation with the working code.

If, instead of having dependent code be hidden in that new worksheet in collapsed Document blocks, all the working code were instead inlined...

I would like to translate Maple's products into Russian and to help russian users in Maple's education.

I am using Maple 14 in Windows xp.

If you enter an equation, or expression into a table the screen display shows more than adequate amount of blank space remaining in that particular table row.  However, when you look at the document in print preview or after printing it out you find that the free space in the row is not correctly displayed.  This is by no means subtle.  For example, I enter an equation into a table and it looks like at...

I sometimes like to use Maple help online as it allows for enlargement of font size very easily.  However, there is no text wrapping and makes reading difficult.

A certain "competitor" to Maple has started offering a "Home" Edition of their product for a very attractive price...I use Maple at work, but love to tinker with individual research.  Supposedly, this edition is the same full-featured product as the commercial and academic versions.  A "Home" Edition of Maple would be *awesome*.  I'm not prepared to jump ship to that "other" product, given the knowledge capital I have of Maple, but I've started entertaining the idea...

This is in the "Product Suggestions" category since there is no better place to report a bug that I could find.

In Maple 14 using the GraphTheory package on isomorphic (but not identical) transitive 3-regular graphs of order 120,

  IsIsomorphic(G1,G2) hangs.  It seems to do okay if the graphs are not isomorphic (returns false), or if they are identical

  in their labeling (returns true).

A suggestion to fix it would be...

Hi!

I'm trying to fit a model with 3 ODEs and 7 parameters to a dataset using GlobalSolve as shown in the code pasted below. Unfortunately, after fitting for approximately 10000s I get the error message:                 System error, , "PopErrorProc"

I tried to find out more about this error message on the internet but I only found that a system error indicates an internal Maple bug.

With MapleSim it is possible to simulate electronic components. But it is not possible to build a model from an existing electric layout. This means, I have to copy for each electric part the data from the datasheet by hand and to connect them. For simple layout this is time consuming, for complex layouts it is impossible.

There are Layout software like EAGLE ( http://www.cadsoftusa.com/index.htm.en ) to build up complex electric circits, with the data and geometry...

The HDF5 file format offers a lot of advantages for data management, particularly with large scientific datasets.  It is provided by the HDF Group [http://www.hdfgroup.org/].  MATLAB and R have routines to load datasets from HDF5 files into memory.  It would be great to have the same capability in Maple.  Has any work be done to import and export Maple data and HDF5?

It appears this has come up quite a number of times (I have even wished this option existed for some of my worksheets).

There is no option to set the pixel size of a window for the plot as an option.  You must use your cursor to adjust the size of your window.  Even globally set the window size as I believe someone has mentioned before would also be a nice addition.

with(plots):
a:=[2.5,2.5,2.5,2.5,5,2.5,2.5,2.5,2.5];
b:=Matrix(3,3,a);
matrixplot(b)

Two corners have been drawn differently.  Shouldn't it be symmetric?  This appears to be a bug

Here's one view showing the sides cut away

and the other view of the other corners, rotated 90 degrees, to show what it should look like.

This is a view I would expect to see all around however the corner in the forefront and the one you can't see have been cut away as I've shown in the rotated view above.
