Hi,

    This is a silly quesiton, but I'm stuck on it. I have 4 vectors of length 16. I want to plot the 16 elements in different colours against the vector number (n=1..4). And assign the same colour each time to each element, i.e color( V[7, n=1] ) = colour( V[7, n=3]  ). How do I do this? 

Thanks!

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...

Hi,

     I'm trying to estimate a very diffcult integral with Maple. Here it is

restart;
chi:=Pi/2-theta:
epsilon:=0.001: 

Vsi:=-(1/sqrt( 1+epsilon - cos(chi)*cos(phi-Pi/3)) + 1/sqrt( 1 +epsilon- cos(chi)*cos(phi-Pi))+ 1/sqrt(1+epsilon-cos(chi)*cos(phi+Pi/3)));

evalf((Int(Vsi*SphericalY(3,2,theta,phi)*conjugate(SphericalY(2,1,theta,phi))*sin(theta), [theta=0..Pi,phi=0..2*Pi])));

I ultimatly want epsilon->0,...

Hi,

     For some reason Maple won't compute the eigenvalues to my matrix, which contains complex numbers and 1 symbolic parameter (h). heres the code

elements:=[1.+0.*I, -0.1e-5-0.4e-4*I, 0.2e-3+0.*I, -1.*10^(-7)-0.4e-5*I, -0.1e-5-0.4e-4*I, -0.1e-2+0.2e-4*I, -3.*10^(-7)+0.3e-4*I, -2.-0.2e-5*I, 0.3e-3+0.*I, -3.*10^(-7)+0.3e-4*I, 1.+0.*I, 6.*10^(-7)-0.2e-5*I, -1.*10^(-7)-0.4e-5*I, -2.-0.2e-5*I, 6.*10^(-7)-0.2e-5*I, -0.3e-4-9.*10^(-7)*I]:

Hi, 

   I'm solving two equations and two unknowns with fsolve where there are multiple solutions (at most 3). I iterate this and my next set of solutions depends on the previous one. The problem is the the first solution (the only one I need) may be arbitrarity close to to the previoius solutions and fsolve skips it and finds the second solution. Any recommendations or ways of makign fsolve resolve arbitrarily close solutions?

Thanks,
