Hi I wonder if anyone knows of any maple code to generate polynomials with algebraic constants. eg an order 1 poly would be: a+b*x, order 2: a+b*x+c*x^2, order 3: a+b*x+c*x^2+d*x^3, ...... etc what i'm looking for is a procedure where i input the order, eg 3, and it spits out a+b*x+c*x^2+d*x^3 thanks in advance

I bought the student version of Maple 11 last week, loaded it onto a Windows Vista machine, and used it for a few days. I had an occasional crash to the desktop, which became frustrating. Upon discovery there was a specific Vista update, I downloaded that, uninstalled the original version, installed the new one and activated it. Now, Maple does not run. If I try to start it nothing happens. No error message, nothing. This occurs regardless of how I try to start it (e.g. "Run as administrator" or not, with UAC on or off). If I try to reinstall Maple, I get the message telling me to first uninstall the previous version, but the uninstaller has the same problem as Maple itself...it will not run.

I need help. A homework problem superimposes a graph atop a DE. What am I doing wrong: _____________ plot1 := phaseportrait(eqn,y(x), x=-0.25..0.25, [[y(-1/2)=2],[y(3/2)=0]],titlefont=[TIMES,ROMAN,18],title=`Sec 2.1 #17`, color=grey, linecolor=[red,blue]): plot2 := (1/2)*x^2: display([plot1,plot2]); Error, (in DEtools/phaseportrait) the 'number' option must be specified before initial conditions Error, (in plots:-display) expecting plot structures but received: [plot1, (1/2)*x^2] _____________

I had the pleasure of visiting Oxford while on vacation in England. I regret that I did not get a chance to visit the NAG headquarters there, but that thought gave me the idea for this next blog entry. The Optimization package for local optimization uses as its underlying engine the NAG E04 optimization suite. It is possible to use the Optimization package without knowing the internal workings of the commands. However, for those of you who are interested in such details, it is possible to get more information. If you set infolevel[Optimization] to 2 or higher, the names of the NAG routines (e.g. E04UCA) are displayed. It is useful to set the infolevel value in any case, as the messages provide valuable information about how the computation is proceeding.

The latest MapleCast episode, Can't Touch This, is now available on the Maplesoft website. Stephanie Rozek (that's me) guest hosts as Tom Lee is out exploring new frontiers… Paul Goossens interviews a group from Quanser about their control solutions for industry, education and research.

Maple can convert an ordinary (base 10) number into its constituents using the convert base command. eg 175 can be decomposed to its digits using: > convert(175,base,10) = [5,7,1] my question is "is there a maple command that turns [5,7,1] back to 175". obviously I could pluck out the numbers and multiply by 100,10 etc, but i'd rather have an inbuilt command. Mathematica has a command that does it: FromDigits. rgds

When I used Mathematica in graduate school, I would ubiquitously specialize a variable and then later "un"specialize it. Specifically, for example, I would write v:= x^3; Then, later, when I wanted the symbol "v" to be left symbolically, I would redefine it with nothing following the definition v:=; I forgot the exact syntax, but it was something like this. But, I cannot find this feature in Maple. Yet I badly need it. Currently, for me to recover the use of a symbolic variable name like 'v', I have to CLOSE DOWN MY DOCUMENT and REOPEN IT! Secondly, in Mathematica, I easily evaluated the "independent" variable to a value

The Maple overload command provides a useful mechanism for splitting the implementation of a procedure that operates on different types of arguments into separate procedures. This article describes the mechanism that it uses to select the procedures, illustrates subtle issues, and shows how they can be resolved.

Hi there, So I'm having this strange experience using dchange and then simplify: doing this: Int(Int(F(u,v),u=abs(v-1)..(v+1)),v=0..1); PDEtools[dchange](u=sqrt(1+v^2-2*v*mu),%,[mu]); simplify(%) assuming v>0; gives the sensible answer: -(Int(v*(Int(F(mu, v)/sqrt(1+v^2-2*v*mu), mu = 1 .. -1)), v = 0 .. 1)) But if I try to simplify on the same line as the dchange: Int(Int(F(u,v),u=abs(v-1)..(v+1)),v=0..1); simplify(PDEtools[dchange](u=sqrt(1+v^2-2*v*mu),%,[mu])) assuming v>0; i get -v*(Int(Int(F(mu, v, v)/sqrt(1+v^2-2*v*mu), mu = 1 .. -1), v = 0 .. 1))

Hi, I´m using Maple V11.01 and as OS Windows XP SP2. The font antialiasing function is not working, there is no difference, when the font antialiasing is enabled or disabled in the display options. The fonts are very ugly. Has anybody the same problem or is there a solution ?

What is the command which returns the length of a list? i.e. length of [1,2,3] is 3 ? More importantly, please tell me where in the help menu this command is listed. Thank you.

The latest edition of TUGboat (vol. 28 no. 2, 2007), the journal of the TeX users group, contains an article by Edward Reingold, Writing numbers in words in TeX, which, as its title states, gives TeX macros for converting integers to names. In this case, American English names. For my amusement Sunday I wrote the equivalent procedure in Maple.

Whenever I try to copy and paste between two worksheets in Maple 8, Maple crashes when I attempt to save the file following the paste. The paste operation appears to work; it is only when I go to save the file that it crashes. Is this a font related problem? Is there any way around this that will preserve the format of the text? Thanks!
