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...

Hi,

Previously I got some great help from Markiyan Hirnyk who introduced me to the DirectSearch package. I am having a little trouble implementing it for this function:

y := proc (E) options operator, arrow; -_C4*MathieuS(-a, -q, E)*(Int(MathieuC(-a, -q, E)*(-a+2*q*cos(2*E)), E))+_C4*(Int(MathieuS(-a, -q, E)*(-a+2*q*cos(2*E)), E))*MathieuC(-a, -q, E)-_C2*MathieuC(-a, -q, E)-_C3*MathieuS(-a, -q, E)-_C4*MathieuS(-a, -q, E)*MathieuCPrime(-a, -q, E)+_C4*MathieuSPrime(-a, -q, E...

Today I have received this e-mail:

Hi Mark,

You very kindly helped me out with an optimization type problem I had a few weeks back. Thanks for that! (http://www.mapleprimes.com/questions/146802...

Hello,

I have been trying to plot a catenary for two boundary conditions. The plot shows the position of the cable but the solution is complex for part of the domain. For the part of the domain where the solution is complex, the plot is empty. Other boundary conditions give me a real answer, but I do need these ones... I have tried running my files multiple...

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

Hi,

I'm preparing for GRE and i came across this question from 800score.com while reviewing concepts for probability.

In a deck of 52 standard playing cards, what is the probability that pulling a single card from the deck 

will produce a black card?

How to update this code to the Statistic Package for the graph below?for n from 1 to 15 do num:=convert(evalf(n), string): tracker[n]:=textplot([18,0.3,`Lambda is `.num],color=blue): H[n]:=ProbHist(PoissonPDF(n,x),0..25,26): N[n]:=plot(NormalPDF(n,n,x),x = 0..25):  P[n]:=display({H[n],N[n],tracker[n]}): od: display([seq(P[n], n=1..15)], insequence=true,title="Normal Approx. to the Poisson. Lambda is increasing from 1 to 15");

I suffer from floaters, (objects that appear in ones vision), a condition that is worsened by looking at white surfaces.  Is there a way of changing the background colour of a maple worksheet from white to a darker shade, perhaps a light grey or something?

Hi,

I have this equation:

gammainc(5,x) = pf

pf = [24*10^-4    120*10^-4    24*10^-3    120*10^-3    24*10^-2    120*10^-2    24*10^-1    120*10^-1    24*10^0]how to find the values of x for the corressponding pf?

Thank you

Hello,

I like to plot the Bode diagram of function transfer. For that purpose, i use Dynamicsystem package.

I obtain my transfer function by 2 different methods : 
- direct method
- state space method.

The issue is the fact that i don't obtain the same results with the 2 methods.

I want construst a vector with 2^62 entries. Only 2^20+1=2049 entries are non-null complex numbers and others are all zero. Maple tells me the memory is not enough.

Recently I was able to try Maple 17 beside Maple 12.  There were little wiggles in 17's plot but not so in 12's.  I thought what if I dragged 12's plot into 17's?  What would I get?  Well here is the result.

I made a plot of x^2+10 in Maple 17 and a plot of x^2 in Maple 12 then dragged the line over. And this is the visual I got

A reddit user posted an interesting question:

http://www.reddit.com/r/math/comments/1eyx0f/help_with_simplifying_in_maple/

The problem is how to simplify, e.g. 2/3*37^(1/2)*sin(1/6*Pi+1/3*arccos(55/1369*37^(1/2)))+2/3 to 4.  I tried a few things and got nowhere.  Any suggestions?
