Hy, 

I'm trying to display a list value in a maplet. But I can only manage to get textboxes, checkboxes and textfields. I know that in textfields I can display the evaluation of a function, but I tried many different ways and I still don't get the desired result. 

I designed a maplet with a button and 6 rows with a checkbox at the end of each row. When clicking the button I would like that the values of a list ("lstx", 6 values) are displayed in the 6 rows. Can you help me? thanx!!

I want to plot a graph of different values of k=0.1,k=0.5, k=-0.1, the display should be like this

my codes are 

restart:

V := exp(-x)*y^3/eta^3:

eta:=1+k*x+sin(2*Pi*x):

x:=0.1:

k:=0.1:

p2:=plot(V, y = 0 ..eta):

tf:=plottools:-transform((x,y)->[y,x]):

tf(p2):

plots:-display(tf(p2),labels=["v","y"]);

I wanna solve a collection of linear systems Ax=b_i, i=1..n, with A an upper triangle matrix, parallelly with Maple. Is there anyone can give me some suggestions? Thanks lot.

In this article I want to discuss the right way to store and build Maple code.

As mentioned in the Introducing the Maple IDE post, over 90 percent of the algorithms built into Maple are implemented using Maple language. The code of the algorithms is stored as Maple Libraries (.mla files).

As

would like to draw the pdf, however after tried two methods, still can not draw it,

how to draw?

l := [binomial(349,20), binomial(349,8),binomial(349,22),binomial(349,38),binomial(349,49),binomial(349,36),

binomial(349,59),binomial(349,41),binomial(349,32),binomial(349,21),binomial(349,23)];

sl := gfun[listtoseries](l, x, egf);

g := convert(sl, ratpoly);

g := g - subs(x=0, g); 

i invent a method to make use of gfun 

as i know series are the number of ways 

however, after i input the number of balls in each box

calculate into binomial and input into gfun, and plot the graph, the problem is value too big 

cannot plot 

however, if using the count directly as input, the graph can be ploted, however, this is not

the logic of my understanding

if input series are not binomial, what are they?

would like to normalize it, how to find x such as 5.6 in this example

l := [20,8,22,38,49,36,59,41,32,21,23];

sl := gfun[listtoseries](l, x, egf);

g := convert(sl, ratpoly); 

g := g - subs(x=0, g);

g := g/subs(x=5.6, g); 

i am very bad at English so you ignore my mistake

i am beginning start use Maple therefore i don't know use Maple.

Like title, i have a circuit CLR with transer function H=

At some point a version of the Maple Player (for the PC, rather than iPad) became available for download from its webpage.

One of those vexing things that should be easy:

I am reading in a data file using ImportMatrix. Since the file has one column with texual data I cannot use datatype=float since that bombs. I >can< ImportMatrix with datatype=string or anything.

I then extract columns using the appropriate command and want to do something numeric with them (only with those columns that have correct floating point numbers). That fails since my data are now not floats (even when using anything...

Hi,
How do I complete the integral below? I'm not sure what the resulting function looks like, but it will be a function of n where epsilon is a real constant. My ultimate goal is to graph the resulting function where epsilon is equal to -0.4.

Thank you.

Hi, 

in my programm I've got a maplet with 6 CheckBoxes, but I can't manage to get the true/false-values in a list to use them. I think I should define a list, I tried:

BoxRow(...

   GridLayout([

      [CheckBox['CB1](), "Box1"],

      ....for all 6 boxes...

])),

lstW:=['CB1','CB2',...for all 6 boxes];

But all I get is: Error, `:=`unexpected.
