MaplePrimes Questions

At the start of my program I specify values for the parameters beta, Q and P. These values are used in calculations in the program. At some stage I then get a list from which I make a selection of elements that have positive imaginary parts. To illustrate. Here I assigned beta := 3; Q:=100;P:=100.

This is my list.

t1a := [VectorCalculus[`*`](sqrt(VectorCalculus[`*`](VectorCalculus[`+`](VectorCalculus[`+`](VectorCalculus[`*`](1440004, Pi^2), 9), VectorCalculus[`-`...

i find that modulo is (Im(M)+Im(N))/Im(N) but where is Im command in maple?

after tried the following package, also not correct, i guess i should use quotient and Im command

with(MTM):
with(LinearAlgebra[Modular]):


Hom := proc(M, N)
Mdim := Size(M);
M_n := Mdim[1];
M_m := Mdim[2];
Ndim := Size(N);
N_n := Ndim[1];
N_m := Ndim[2];
F := kontraHom(M,N_n);
B := kohom(N,M_m);
C := kohom(N,M_n);
D := Mod(F, B);
E := Mod(D, C);

I am using the LinearAlgebra package. The function SinbularValues returns the singular value matrix S as a vector, i.e.,S*<1,1,1..1>.  Is there an easy way to recover S, itself, from this vector?

Hello,

In Maple 15 "Document" mode, how may I create a 2D fraction as *text* (as opposed to mathematical input that Maple evaluates)?

Thanks,

Hello,

My name is Jonas, and i'm trying to do some calculations on bending of a aluminium frame. Now i'm really confused why it wont plot! 

I attached my maple file. I hope my question is clear! 

Thanks in advance!

i find a link http://en.wikipedia.org/wiki/Exponential_integral

in the link, is Ei(x) = Ei(1,x)?

is Ei(1,x) called exponential integral?

what is Ei(2,x)?

what is definition of Ei(y,x)?

Hi,

i have two equations from these following type

 

Hey, any help would be much appreciated! For any 2x2 matrix A, I can use GaussJordan(A) and it will return its reduced form. But I want to write a short program that will return the elemtary matrices used during the process as well. Any idea how to do this?! Thanks!

I should need to solve the transcendental equation below in the unknown  theta0(k+1) , I am not 
able (Warning...). Is there any trick to solve it ? Why in this case Maple output is:
Warning, solutions may have been lost ????
 

solve(0.4254750000e-2*theta0(k+1)/DT^2+(-0.2500000000*sin(theta0(k+1))*lambda1(k+1)*
DT^2-0.4254750000e-2*theta0(k...

I need to install Maple 8 for the Mac OS. Would you let me know where to obtain it? Thank you very much!

Hi,

I need some help, I have tried some variants of finding of min of an array but it did not work.

I have declared an array (T:=array(1..10), then using a cycle to calculate the values of this array. I can read this array and plot the data and see the min and max values(for example: (1,2,0,3,4,5,6,3 ,-1,5)), but I can not automatically calculate  the min and to find that this is exactly T[9].

Is there special function that I can use for this or...

Why the Maple, the power of zero to zero 1 and I do not indeterminate? thanks Zampiva Diego

For example, I have the expression:

f:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6)+5*ln(5*r)*Pi+5+x;

How to isolate terms in i and other terms (automatically) to get :

f1:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6);

f2:=5*ln(5*r)*Pi+5+x;

Thanks in advance

I am trying to take the inverse fourier transform of a dsolve/numeric in Maple 15 and I'm wondering if there is a way to do something similar to the fftshif in Matlab.

Here is the sheet so far, the fft's happen at the very bottom.  (any advice on the flow/syntax of the sheet is welcome too)

Hello everyone

It seems I can't live without keyboard shortcuts :-) Is there is a short cut for the following commands:

 

execute the entire worksheet
remove output from sheet
join/split execution groups

 

I'm on mac.

 

thanks.
