Yes, it's probably an installation issue. Please check your Maple_13_InstallLog.log on Linux. If it lists any errors (including non-fatal ones; see the Summary section first), you should reinstall. This solved the issue for another customer who had reported the same error message for plots. His installer from the webstore turned out to be broken, so a fresh download fixed this.

I'm now working in the new office, including technical support.

Just a side remark: you can use kernelopts(datadir) to keep such worksheets platform-independent.

Note that a single forward slash also works on Windows, as in cat(kernelopts(datadir),"/images/phone.jpg")

That code can be found in the Help > About box; see the "Serial Number" field.

The amount of extra work can be reduced through plots[setoptions].

If you are looking for Wirtinger calculus, please check out the Maple Application Center. There are several worksheets treating this topic.

If I understand your posting correctly, then it's not a surprise since the XPM in Windows 7 is just a virtual machine with some additional integration features, AFAIK.. We will have such a system installed in the next few days.

Windows 7 will be supported from Maple 13.02 on, so you can maybe avoid the XPM feature altogether.

Note that the MTM does not yet support R2009b.

You can explicitly split pages in a Maple worksheet, and these markers are being used in PDF export as well. Just press Ctrl-Enter, or (equivalently) select Page Break from the Insert Menu. Enter ?pagebreak to open the documentation page.

I think I will develop the portfolio optimization in MATLAB instead which can perform numerical computations much faster.

Depends on the problem, probably. Certainly not in general (one of our customers has impressive counterexamples).

I think global optimization is free in MATLAB  which is not the case for Maple kilo $$$$$ which I dont understand why ?!

I'm not a MATLAB expert, but I was told that global optimization is not included in it. Certainly the LGO library (the base of the Global Optimization Toolbox for Maple) is not included; see its developers pages at www.pinterconsulting.com/.

First, note that Maple interprets pi as a greek character with no special connotation. For the mathematical constant, use Pi instead.

As for the simplification of cos(Pi/2) versus cos(Pi/10), some rational multiples of Pi are treated automatically, while others are not because the resulting expression could be rather large. If you explicitly want that, try

convert(cos(Pi/10),radical);
