I have a column vector of lists. FWIW, it was generated by numerically solving an ODE and then map-ping the solution over a vector with values for the independent variable, like "yt:=map(solnn,xv)" where xv is a column vector with floats and solnn is the result of a dsolve(...,numeric). Each element of the solution vector yt has the form [t=..., y(t)=..., d/dt(y(t))=...] and has the type List.

I want to extract the solutions for y(t) (i.e. the numbers only) into a new...

i am modeling a simple standing wave. i have created three plots y1, y2 and y and then i am using animate to move them. the problem is that i cant add a legend describing every plot and i am not getting how to do this.

in addition when i click on the plot and then go to the legend menu, both show legend and edit legend are disabled.

here is my code

with(plots): y1:=0.01*sin(Pi/2*x-40*Pi*t);

                 y1 := -0.01 sin(-1/2 Pi x + 40 Pi t)

I'm very new to maple and i want to use DEplot to plot phase portraits.  how do i do this? I am using maple classic.

When maple does gauss elimination for matrice(student linalg). In "edit matrice" can i solve for x1,x2,x3..?

Hi there,

I am trying to find an analytical solution to an integral. Unfortunately, I only get the function call returned. Is there anything I can do to get Maple to solve it?

Thank you

Hi! I have 4 function. I wanna plot two of them in x=-0.5..0 range; the other two in x=0..0.5 range. How can I display that four function in one plot? Thanks!

How to perform the following plot in Maple?

Hello, I cannot import a 4 Mb file   (https://skydrive.live.com/redir.aspx?cid=8fc13b21d305c1b2&resid=8FC13B21D305C1B2!112&parid=8FC13B21D305C1B2!107&authkey=!AMlLjsY6PHKn5AQ)

(that is a symbolic expression I'd wish to manipulate) taken as a single element of a list  by  a:=ImportVector("dinner.txt", datatype = anything);

kernel says it cannot interpret file.

Is there a limit in the input file dimension ?
 It's...

I have a 6x6 matrix that depends on 8 parameters, M(F) (F is an 8-dim array, say...), and I want to compute the eigenvalues of this matrix both at a fixed point F_0 and at some other arbitrary point F'. The problem is that I need to make sure the ordering of the Eigenvalues remains the same at these two points, so that if I'd go continuously from F_0 to F' the eigenvalues would go continuously from Eigenvalues(M(F_0)) to Eigenvalues(M(F')), without any flip in the order of the entries.

Dear All,

I would like to know the easiest way to write data, that are stored in a matrix after a computation, to a file with a specific format. To be more precise, I wish to have the possibility to change the format for a given column.

Here is a trial (output is wrote to the terminal for simplification) based on some examples I found, but without success.
