Hi, I am Er. Vishal Jain new to maple prime. I need help in developing dynamic 2D-graphs(pi-chart, conic section etc.) in .mw and respectively shade the graph.

Documentation on how to reference or assign values to elements in Table is limited. I uploaded a copy of a simple code (690_MTable) which tries to assign values to the elements the table. Code does not give and error message but does not do what I wanted to do. Please replace this text with the link to your file. The link can be found in the View 690_MTable.mw on MapleNet or Download 690_MTable.mw

I recently purchased a Maple e-book, and I noticed a few lovely features of which I would like to take advantage. The first is the ability to create a compressed worksheet. There seems to be a painfully simple mechanism behind compressing and uncompressing the worksheet, since when the worksheet is opened with a text editor, the first characters are (if I recall correctly) "<compressedworksheet". I cannot find any documentation inside of Maple detailing the compression and uncompression of files. Thus, I ask you, Maplesoft: How can I compress my worksheet files in this manner? The second feature of which I would like to take advantage is the use of a license file. Looking at the XML code of the compressed worksheet, it seems that one only needs to make reference to the location of a license file in order for Maple to look for the license file. The license file itself is very short--only about 4 lines--which makes me assume that the license file checking mechanism is similarly simple. Again, Maplesoft: How can I make and use my own .dat "license" files?

I am trying to plot the equations shown in Figures 5 and 6, which are solutions to Equations (14), (15), and (16). These equations are developed in the Lo paper (attached). I am working through the symbolic solution by hand and would greatly appreciate any suggestions on how to set these equations and the graphs of the same in a worksheet. Thank you for the assistance anyone may offer. Wayne Bell Download 4865_Lo_p691.pdf

Sooner or later, you'll like see the following "tip" in with the tips that load when you start Maple, but in case you've overlooked it you should really give this one a try. Just type in: ?examples/index

This may have already been resolved but in case some people are still having problems... If your maple calculator is not working (ie not giving you an answer .. just giving you a blank line) your firewall may be blocking the java.exe script in your maple\jre\bin directory. Just allow access for this file. So just create a new rule in your firewall to allow full access for the maple\jre\bin\java.exe file and voila your calculator should now be giving you some answers. Hope this helps. And sorry for posting again if someone already mentioned this in the past.

Is there a keyboard-only way to enter equation labels that will not 'zap' the focus away to a dialog box just to enter a label? While the 'look' of the equation labels is kind of nice, I find entering them extremely annoying (zapping focus is really awful UI design).

I observe that within graphics numbers are displayed according to local settings (so 0,001 stands for 1/1000) - no problem for me, but annoying, actual output displays with a point as decimal separator. For pretty display I sometimes use something as 'eval(expr, x=1)': '%'=% which works fine in mws, but in mw it displays the eval statement - is there a workaround for both kinds of sheets? And saving a mws as mw does not respect the font size for 2D output (it changes mine from 10 to 12 (and behaves odd, it always uses italics, but we had that already i think). (Win XP home SP2,

I am using maple 11. I have an HP printer which I verified is working corrrectly. I have a document made in document mode that I stored in a file, and when I print it sometimes it comes out ok and sometimes it comes out with everything about double size and I don't know what I am doing to cause the double size. When this happens I go to file, print preview and click on double page, and then single page at the top and everything seems to print ok in normal size again. But now I just completed another document and tried to print it out and it printed again with about double size letters but when I go to file print preview, double page and single page are not enabled and I don't know why and consequently I have no way to print out this document.

Maple Professionals: I wish to prgramm a greedy heuristic in maple and would be more than grateful, if someone could help me, since I am no expert in programming. The problem is a simple stocking problem. There are two parts I wish to stock in my warehouse. I know their demand, delivery time and item cost. From the demand and the delivery time I can calculate the expected backorders given a specified number of units in stock based on a poisson distribution. In the greedy heuristic step by step I increase the stock of all items by 1 and then calculate the reduction in expected backorders divided by the item cost (some kind of "bang per buck"). I then compare the reduction over all items and increase the stock by one for the item with the highest reduction.

How do I use Maple to apply depth-first search to a graph to obtain a depth-first search of numbering of the verticies. Once again I need to input my graph in order to retrieve this information. How does Maple provide this info based off my graph?

This is my system: rho * diff(diff(delta(x, y, t), t), t) = (y ^ 2 / 0.2e1 - d ^ 2 / 0.8e1) * Y * diff(diff(diff(diff(xi(x, y, t), x), x), x), x) + (((2 * G + lambda) * v - lambda) * diff(diff(xi(x, y, t), x), x)) + 0.16e2 * Q(t) ^ 2 * y * (d ^ 2 - 0.2e1 * y ^ 2) / d ^ 4 / b ^ 2 / l ^ 2 / e; diff(delta(x, y, t), y) = v * y * diff(diff(xi(x, y, t), x), x); i = 0.8e1 * Df * Q(t) / d ^ 2 + l * Lp * (int((2 * G + lambda * (v - 1)) * diff(diff(xi(x, y, t), x), x), x == (0..b)) + Y * d ^ 2 * int(diff(diff(diff(diff(xi(x, y, t), x), x), x), x), x == (0..b)) / 0.12e2) + diff(Q(t), t); My objective is to obtain the expression of delta,xi and Q to the space coordinates(x,y) and time,t.The other letters are constants. Can the maple do this? I try with pdsolve but obtain this error:

I need to solve following ODE: ODE:= y(f)*(diff(y(f), f, f))+50.0*f -50.0*f^2= 0 Subject to boundary conditions: BC:= (D(y))(.5) = 0, y(0) = 0 I used BVP method : dsol2 := dsolve({ODE, BC}, numeric, method = bvp[midrich], y(f), range = 0 .. .5) But I got " Error, (in dsolve/numeric/bvp) division by zero" Can someone please tell me what I can do.

Something I hadn't tried until today was calling into a DLL with Maple. I was surprised at how easy it is. Once inside a DLL, the sky is pretty much the limit as far as passing the data around between applications for realtime plotting and even passing to device drivers for other processing or even I/O in WinXP.

Is it possible to get/set the view option of a plot component using the DocumentTools package? I'm trying to plot a function containing a parameter whose value is controlled by a slider component. When I adjust the view using rightclick->manipulator->scale and then move the slider, the graph reverts back to the hard-coded scale in the original plot command. I'd like to set a default scale, then allow a user to set the scale using the scale manipulator and have that new scale persist through the next slider manipulation.
