Hi everyone,

Here is the code:

Ralpha:=sqrt(d)*IdentityMatrix(2):

alpha:=Array([WienerProcess(Ralpha),WienerProcess(Ralpha),WienerProcess(Ralpha),WienerProcess(Ralpha)]):

alpha1:=k->Vector[column]([[alpha[1](k)[1]],[alpha[1](k)[2]],[alpha[2](k)[1]],[alpha[2](k)[2]],[alpha[3](k)[1]],[alpha[3](k)[2]],[alpha[4](k)[1]],[alpha[4](k)[2]]]):

Finance[ExpectedValue](alpha1(0)[1]*alpha1(0)[1],timesteps=100,replications=10^4);

I have a rather large multivatiate polynomial "Dtest" I need to divie it by a cubic poly "DGm" using rem and quo. Both are determinants multiplied out, both given below. Have spent the past 2 nights trying to sort, collect, expand, equate coefficients plex groebner etc. Am trying to collect up all the powers of c_{3} but cant anything to work. even expand doesn't fully expand "Dtest". If I set c_{1} and c_{2} to 1 things are...

I want to find the diffrential equation of

I have to solve a linear system

in Maple. A is a tridiagonal matrix.

My problem is that my matrix A is big and therefore, I have to wait too long. Is there some function in Maple that can help this problem?

Hi, I'm trying to visualize a 3-Dimensional function, the color being the 4th dimension. All the examples that I have found of the so called plot3d function only involve 2D functions, the third dimension really being the return value of the function. I need more: I have a 3D function which takes in (x,y,z) if you like, and outputs one number. I'd like to visualize this function in maple.

Thanks, ~Austen

Hi,

See the code mli.mws

What is the mistake in this command ?

chfonc:=cat('piecewise(' , seq(cat(convert(t<lf[k],string) , ' , 1 , ' ,convert(t<lf[k],string), ' , 1 , ' ) , k=1..p) , '1) ') :

scatter2d quantile2 scatter1d is removed?

with(stats): with(statplots): with(transform):with(random): with(describe): with(plots):datax:=[normald[5,1](100)]:datay:=[normald[7,3](100)]:scatter2d(datax,datay);quantile2(datax,datay);scatter1d(datax);scatter1d[jittered](datax);who(things) replace it?

I hope someone can help me.

I'm trying to integrate the following equation: sin(v)*sqrt(cos(t)^2+4*sin(v)*sin(t)*cos(v)*cos(t)*sin(w)+4*cos(v)^2-cos(w)^2*cos(t)^2+cos(t)^2*cos(v)^2*cos(w)^2-5*cos(t)^2*cos(v)^2)

The boundaries are v=0..1/2*Pi w=0..2*PiThe exact command I'm using issimplify(int(int(sin(v)*sqrt(cos(t)^2+4*sin(v)*sin(t)*cos(v)*cos(t)*sin(w)+4*cos(v)^2-cos(w)^2*cos(t)^2+cos(t)^2*cos(v)^2*cos(w)^2-5*cos(t)^2*cos(v)^2),v=0..1/2*Pi),w=0..2*Pi);

Hello,

Suppose that S1,S2,S3 are 3 blocks of a matrix S := Matrix(...). I would like to do

out := ArrayTools:-Concatenate(2,convert(S1,vector),convert(S2,vector),convert(S3,vector)):

but in the case when I have n blocks.

Thanks,

Dimitar

I am aware of how to plot the feasible region defined by a system of linear inequalities (inequal in the plots package). Also, I can use the implicitplot command to plot the feasible region defined by a single nonlinear inequality. My question is, how do I plot the feasible region defined by a system of nonlinear inequalities. For example, how would a graph the region satisfying x>=0, y<=exp(-x), and y>=x^2?

I'm trying to integrate the following equation: sin(v))*sqrt(cos(t)^2+4*sin(v)*sin(t)*cos(v)*cos(t)*sin(w)+4*cos(v)^2-cos(w)^2*cos(t)^2+cos(t)^2*cos(v)^2*cos(w)^2-5*cos(t)^2*cos(v)^2)

The boundaries are v=0..1/2*Piw=0..2*Pi

I've tried evalf and simplify, but none of those worked. Does someone know how to solve this one?

I have program in txt,I want to copy it into the command-line maple 15 as belows:

How to do it. Ctrl+V is uselesscode:> MEMBER := proc(x::anything, L::list, p::evaln) local i;> for i to nops(L) do> if x=L[i] then> if nargs>2 then p := i end if;> RETURN(true)> end if> end do;

Hi all,

I am trying to check a conditional statement in maple, I know it is true but my teacher has us do the entire assignment in maple. I am proving the alternating series test of convergence for a series and need to show that the Un's are all positive so

I am trying to check this statement for truth:

5/sqrt(x+4) > 0 for all real values x > 1

HiI run Maple 15 on an Acer laptop with Windows 7 and have the following problem:When my Maple documents become "too" long, some of the vectors I have created seem to become tables instead (without me doing anything) rendering vector multiplications and additions/subtractions impossible (they'll throw an error; something like it not being possible to multiply a vector and a table. As if one of the vectors in my multiplication has become a table). Should it...

Can maple solve this kind of inequality:piecewise(x > k, x-k, 0) > q * piecewise(x*(1+a) - k > 0, x*(1+a) - k, 0) + p * piecewise(x*(1+b) - k > 0, x*(1+a) - k, 0)where p, q, a, b, k are parameters?

I'm trying solve-command with allsolutions option but it doesn't work :(

Thanks for answering :)
