I was trying to generate a derivative of randomized order in Maple T.A.
It seems impossible to me since the $ in the Maple syntax of
diff(function,x$n)
and the $ in the Maple T.A./brownstone syntax needed to denote a variable are incompatible.

Coding, for instance,
$n = range(2,5,1);
$function = maple("diff(x^5,x$($n))");
or
$n = range(2,5,1);
$function = maple("diff(x^5,x$$n)");
in the algorithm section makes Maple T.A. complain about a syntax error immediately

Coding
$n = range(2,5,1);
$function = maple("diff(x^5,x$n)");
leads to
jvm 1 | To Maple --> diff(x^5,x2)
being passed to Maple (taken from wrapper output).
Hi everyone! I would like to create a worksheet witb multiple worksheets, and I would like to use sections and subsections. Can anyone please tell me how to lock certain sections/subsections closed so users cannot open then? Thanks :)
Hi everyone! Does anyone know how to get Maple to automatically evaluate expressions to a decimal approximation, instead of printing the value with square roots, and 'pi'? Thanks!
Hi! Could someone please tell me how to : Use hyperlinks to refer to other sections with the same worksheet? Thanks :)
Hi dear members of this Forum,

I want to generate a list which depend on "n";
for n=2 I would like to generate the following list

>[[p1>q1, p2>q2],
>[p1>q1, p2<q2],
>[p1<q1, p2>q2],
>[p1<q1, p2<q2]]

for n = 3 I would like to generate the list:

>[ [p1+p2>q1, p1+p3>q2, p2+p3>q3],
[p1+p2>q1, p1+p3>q2, p2+p3<q3],
[p1+p2>q1, p1+p3<q2, p2+p3>q3],
[p1+p2>q1, p1+p3<q2, p2+p3<q3],
[p1+p2<q1, p1+p3>q2, p2+p3>q3],
[p1+p2<q1, p1+p3>q2, p2+p3<q3],
[p1+p2<q1, p1+p3<q2, p2+p3>q3],
[p1+p2<q1, p1+p3<q2, p2+p3<q3]]

for n=4

[ [p1+p2+p3>q1, p1+p2+p4>q2, p1+p3+p4>q3, p2+p3+p4>q4],..
If I have the X and Y variable all done up and I am trying to find a way to figure out if their is a way to make up a quadratic equation with maple. and can maple find the inflextion point of this curve ? Any help would be appreciated. Thanks Jp
is it possible to implement a package so that the documentation and the help files will be automatically extracted from the sources?
Hi everybody ! I'm trying to sort a matricial expression : J=u'*Q*v (the ' is for the transposition, and * the matrix product) where u=A*x+a and v=B*x+b (Q,A and B are (3,3) matrices ; u,v,x,a and b are (3,1) vectors ; so J is a scalar) I want to stay in the formal field ,i.e I give no numerical values to my matrices an vectors. What i would like to do is to write J like : J=x'*K*x + Lx + M where (that's the result I found by hands) : K=A'*Q*B L=b'*Q'*A+a'*Q*B M=a'*Q*b And of course I would prefer Maple doing it for me ! :) As I really don't know how to take the problem, I tried very easy things :
Hi dear Maple's experts, 1.- If I have a variable r0 := x^3, Then, I can save r0 in a file: save r0, "myFile.txt"; Now, if I have some additional variables r1:= y^2+ 10; Is it possible to add r1 to the previous already created "MyFile.txt" (without overwriting the initial file)? 2.- When I work in Maple 10 (worksheet mode).. I woult like not to have to press "F5" to switch from "C 2D Input" to "C Maple Input" . Is it possible to set up "C Maple Input" as default option to write the comands? 3. When I write usually the commands appear in red.. and output appears in blue..It is possible change this colours?.
As a newbie to maple, I was wondering how do I find the maximum of a equation under contraint. i can find some but for this one I can't ... and it's getting to me f=1000*x+7500*y under constraint: g=10000000-(20000*x^0.8)*y^1.2 and for f=(20000*x^0.8)*y^1.2 under constraint: g=125000-1000*x-7500*y Who do I find the maximum using MAple 10 !!!???? Tx for the help
Hi All, I have the following graph: plot([(x/(2*sqrt(x)-3)),(-x+5)],x=-10..10,y=-4..6,discont=true, color=[red,navy], thickness=2); how do I a) label the two functions so that they are visible in the graph i.e. L=-x+5 beside the blue line and f(x)=x/(2*sqrt(x)-3)) in pretty text beside the upper red function? b) I wish for a dashed blue line (-x+5) instead of constant. Thanks in advance for any help :-) Robert
Does anybody know how to install the 10.02 update on a 64-bit version of Maple? -- Regards, Franky.
We have an automated grading system and sometimes students assign values to variables that are useful in grading their assignments. In order to get around this I've been tinkering with the anames() command (specifically, anames(user)), but I cannot seem to get a usable list of "in use" variable names: Every time I try to get Maple to use the list that anames(user) returns, I get the evaluated variable and not the variable name. Example: >a:=4; >anames(user)[1]; 4 Does anyone know how I can get a usable list of variable names that have been assigned values?
Hello Maple insiders, I'm still learning to get along with Maple (version 10.01). Currently, I would like to have a small procedure which creates a random matrix of arbitrary dimension with complex floats. However, the generated matix, say A, has to fulfill the following conditions (because it should be a valid physical density operator): 1.) A is hermitian 2.) A is positive semidefinite, together with 1.) this should mean that A has only real and nonnegative eigenvalues 3.) A should have trace equal 1 With the randomly generated matrices I would like to cover (reasonably uniformly) the set of all possible matrices with the above constraints.
Hi, I would like to be able to plot a 3d surface of one variable, with another variable in colour on that surface. This plot should have a legend for the colour variable. At a stretch, I would also like to have all of this in polar co-ordinates, with polar axes and without having to write a transform myself. Is all this possible! cheers
