I have JPG images and plots from a CAD code and from Matlab. I want to insert them into a Maple worksheet and do the following:

      1. Resize the images or plots while preserving aspect ratio

      2. Add a figure number and caption to the image or plot.

          I would prefer automatic numbering if that is available in Maple.

          I would also prefer to have the caption "linked" to the image or plot so that they can be moved together

I assumed that these kinds of tools were available in Maple, but I sure cannot find them. Any help will be greatly appreciated.

Thanks, Neill Smith

I recently upgraded from Maple 2019.2 directly to Maple 2022.2. I now have a problem with any double or triple literal subscripted variable in old worksheets or in new ones under Maple 2022.2. Double and triple indexed subscripts work just fine under Maple 2019.2.

If in Maple 2022.2 I enter X__a I get a proper Xa.  If I enter Y__a,b I get 'Ya,b' Note the leading prime preceeding the Y and the trailing prime following the subscript b down at the subscript level. This behavior holds for triple literal subscripts.

On the other hand, indexed subscripts work just fine in Maple 2022.2. If I enter X[a] I get Xa. If I enter Y[a, b] I get Ya,b .

How do I fix this behavior? When did it start? My jump from Maple 2019.2 to Maple 2022.2 was due to changing companies during the Covid period. I am using Maple on a Mac.

I have not tested literal superscripts or combinations of literal subscripts and superscripts.

Any help will be greatly appreciated. I use literal double and triple suscripts all the time to distinguish between vector and matrix components in different coordinate systems.

My old company went belly up during the COVID period. My old email address is now dead as a doornail.

I can login to MaplePrimes using the old email address, post questions, etc.

However, I can't change my account email address becaue Maplesoft sends a verification message to the OLD email address.

If I post a question, I can read the replies here. However, any replies sent to my OLD email address just disappear.

How do I change my account email address under this situation?

Thanks.

I have created a simple piecewise function to represent the radius r(x) of a circular cylinder of length 2a and radius b with ellipsoidal end caps of length e << a and e << b to get a smooth transition of r(x) at the two ends for use in slender body theory. The piecewise function does not behave as I had expected, and this is the first time that I have used a piecewise function. What am I doing wrong? The attached (I hope) Maple worksheet shows both my expected behavior and the actual behaviort. Any help will be greatly appreciated. Thanks.

## I hope this works. I can't seem to paste my MW file in this window in a readable format.
