Hi,

     I have a a matrix with one symbol and all others are numbers. I got this from doing 

   M := (1-x)*N + x*A :

 So my parameter is x, and N, A are numeric (real, symmetric) matricies. I want to plot the eigenvalues as x=0..1, but for a large matrix, say 25x25. Eigenvalues(M) only returns 17 eigenvalues, and more so, it doesnt keep them in the same order when plotting!

My issue is when Maple computes the...

Hello, I am trying to solve the following BVP,

Eq1 := -mu0*M*(diff(theta(eta), eta))*exp(-M*theta(eta))*abs(diff(f(eta), eta))^m*(diff(f(eta), eta))

+mu0*exp(-M*theta(eta))*(m+1)*abs(diff(f(eta), eta))^m*(diff(f(eta), eta, eta))+theta(eta) = 0;

Eq2 := G*(diff(theta(eta), eta, eta))+mu0*exp(-M*theta(eta))*abs(diff(f(eta), eta))^(m+2) = 0;

bc := f(-1) = 0, f(1) = 0, theta(-1) =0.5, theta(1) = -0.5;

m:=-0.3 (or 0.3) :M:=1:mu0:=0.5:G:=3:

I want to solve the following equation

1+{(25.*phi^3-297.*phi^2+1162.*phi-1500.))*(840.+332.*theta+29.*theta^2)/((phi^4-16.*phi^3+89.*phi^2-201.*phi+150.)*(3.+theta)*(28.+11.*theta+theta^2))}

in terms of theta.

i.e theta=[f(phi)].

Dear All, 

I am doing a simple optimization and I am getting an answer at the end. I want the output of the optimization problem to be assigned to a number instead of a list. Could anyone please suggest a resolution for this?

Following is the code

with(Statistics);

dummy1 := sqrt(1/(1+y*e));

R := RandomVariable(Normal(y*e*z/(1+y*e), dummy1));

 y := 1; b := .3; a := 1.25;  z := 1; e := .2:

with(Optimization):

Hi every one

I'm new to maple programming so my question might be boring. I'm trying to solve the higher order kernel generation function which appears in B. Hansen (Econometric Theory, 2005). The quation is

I'm running Maple 12 on my Windows 7 machine, 64-bit.  I never had this issue before when running in on XP (32-bit) for a couple years before I got a new machine.

Basically, whenever I go to Save or Save-As, Maple just closes.  It doesn't freeze or anything, just closes.  This problem is sporadic - sometimes it happens and sometimes it doesn't.  At first it was only doing it with Save and I overcame the problem by just making multiple versions of...

How to calculate mul(sqrt(3)+tan((1/180)*Pi*j), j = 1 .. 29) exactly?
The command
simplify(mul(sqrt(3)+tan((1/180)*Pi*j), j = 1 .. 29), trig)
is spinning.

Hi,

I have two general 4x4 matrices S and R subject to the given contraints (eq1, eq2, respectively). First of all, I was trying

to see if there are any specific matrices T such that the equation S.R=T (subject to the constraints of eq1 and eq2)

does NOT exist (i.e. there are no matrices S and R such that the equation holds). I tried many examples but couldn't find

any so now I suspect that any possible T has a solution.

So firstly, I...

Can someone provide me a simple code to understand Homotopy Analysis Method for solving PDEs. I am a pure mathematician and came to know that Homotopy has found application in solution of PDE. Kindly guide me, as I can understand through a Maple Sheet much easily than a by a book or research paper. Regards

A few weeks ago, we announced that we had established a partnership with DigiArea, Inc. to bring the Maple IDE to the Maplesoft Web Store.  Development is progressing well, and I'm happy to report that we expect to have the IDE available for download beginning on June 19th.
