Hello, everyone! I would like to find a the unique, reduced grobner basis of a particular ideal. I know that gsolve in the old with(grobner) package would return this, but I can't decipher the documentation of the new with(Groebner) package to figure out how to do it.

If I have a list of polynomials and a given monomial order, I know that I can call:

with(Groebner);

my_gb := Basis(my_I, my_ord)

Hello!

I am solving numerically a non-linear Pde using the command  "pds:=pdsolve(....)"  and all are as they should be...[ pds := module ()...] but when i am trying to plot the outcome i receive: "Error, (in pdsolve/numeric/xprofile) unable to compute solution for t>.188000000000000000:Newton iteration is not converging "

Is there a way to overcome this problem (even if i must lose in accuracy..)???

Thanks!

 

My comp (AMD Athlon 64 Processor 3000+, 1.5 GB RAM) calculates the integral int(1/(x^4+3*x^2+1)^p,x=0..infinity) for p<=545 and the same comp with Maple 10 calculated this integral for p=3000. The answer is of the form k/n*Pi*sqrt(5), where k and m are natural numbers.

How to explain that?

Anyone know how to debug FOR loops in MAPLE? Thanks in advance.

Hi, guys, I want to compare the performance of procedures which are written by myself. But I have no idea how to get the runtime of a procedure. Thanks in advance.

Hello folks i was hoping for a spot of help.

I need to normalize three vectors. Each vector is 1 by 3 in size. Ive started by defining the vector then normalizing it by what i have defined it. The next stage is where im stuck, ive looked through various examples inclduing the one i this link: http://www.maplesoft.com/support/help/AddOns/view.aspx?path=LinearAlgebra%2fNormalize

Does anyone know where V:={1.55,1.56,1.53} comes from?

 I read to *.wav, copy them into two arrays with same size and I'm not able to write it anymore.

Anybody here who can help?

 

with(AudioTools);

with(ArrayTools);

readlib(FFT);

signalfile := cat("C:/Documents and Settings/848380/Desktop/", "klar.wav");

hfile := cat("C:/Documents and Settings/848380/Desktop/", "church.wav");

x := Read(signalfile);

y := Read(hfile);

Preview(x);

Preview(y);

Greetings

Good morning I'm looking for the best way to create an array with four index, let's call it V_{ijkm}, knowing that it is completely independent from the order of the index (eg V_{1234}= V_{2134}= V_{4213} =etc) and that I must use nested for cycles to initialize it, instead of a indexing function I can't guess how to insert the knowledge that the order of index in unimportant in the code Thank for any hints s.v.

Hi boys

Here I'm trying to solve this problem.

#A bar of 1meter of length is placed in a room at 10ºC. At a time t=0 its borders (x=0 and x=1) is placed in contact with Ice at 0ºC and then the system is kept isolated. Show the temperature profile of the bar at each time until t=0.2s#

I want to display the output from printf ( columns as seen below ) in a MathContainer (embedded component) . How ?

seq(printf("%20a  %10a  %10a  %10a  %10a  %10a  \n", i, i^2, i^3, i^4, i^5, rt[i]), i = 1 .. 10);

Dear all,

I'm trying to obtain a 3D graph with Maple starting with 3 experimental variables : IC50, REDOX, LIPO
Here are my list of points and the procedure I wrote.

Hi I've remarked something strange in a program I wrote. It's a mix of analytical and numerical computation, so that I use a value of Digits higher than the default, to improve and stabilize the results against floating numbers errors. What happens is that for Digits from 10 to 15 included, the time the PC needs to run the program increases reasonably, so that for Digits=15 it needs 10 minutes or so. But if I set Digits=16 the time rises exponentially, and becomes more than two days!!

  I am having problems making histograms in maple. It seems that the default Maple command plots a Histogram (that is the command Histogram), with which the area of the bars is overall normalized to 1. How do I get rid of this feature? If I plot the data set (1,2,3,4,5,6,1,2,3,4,5) with a binwidth of 1. I should expect 6 bars each of count 2 except the last 1. However in maple I get something completely strange using the command Histogram(DATASET, binwidth=1). I am using Maple 12.

1) compute the first ten derivatives of f(x)=sin(x)cos(x) using a for...do...od loop. Describe the pattern for the derivatives. Use your description to predict the 2500th derivative form. 2) Expand the do-loop code in the first question to include a command line inside the loop that plots each derivative. The output shows that each derivative is plotted separately. To plot the derivatives simultaneously after the loop has terminated, save the plot inside the loop using a label such as pl[i]:=plot(df[i],x=-10..10_.
