I have a vector M with 1000 values
Now I want to add a certain value N:=100 on each of the 1000 values of the vector, but I do not know how to do that.
Result:=N+M?

Dear experts,
I have a problem which is probably quite easy to solve for you.
I generate 1000 random numbers with the follwing command and save them under R2
R2 := Sample(RandomVariable(Normal(0, 1)), 1000)
Then I take this numbers and convert them with
R2next:=mu1+R2
That means, I want to add mu:=100 on each of the 1000 values of R2. Does somebody know a solution for this problem?The problem is that maple responds: Error, (in rtable/Sum) invalid arguments

I have an issue where in standard interface Maple won't display the extra digits. As an example evalf(10.5) returns 10.5 only.

Hi maplers

I have a problem, since i am printing text in some procedures that i really want to be black and alligned to the left side. It would be a great help if anyone could help me out.

Hello,

I want to display my plots in tabular form. So I have tried it with the display command and I wrote my plots in

an array.

The problem is, that I want to have two plots in the uppper left corner, but the display command ignores the

second plot.

Is there something wrong with my Array or is there another possibility to display plots in a tabular form??

L:=Array(1..2,1..3, fill=plot(x)):

L[1,1]:=plot(x^2), plot(x-1):

display(L);

Thanks for your help.

I want to solve the following system of ODE:

sys := {M*(diff(x(t), t, t))+C*(diff(x(t), t))+(2*Delta/(1+exp(20*(Pi-t)))+KMIN+Delta)*x(t)+((-20*Delta*exp(20*(Pi-t)))*(1/(1+exp(20*(Pi-t)))^2))*y(t) = P, M*(diff(y(t), t, t))+C*(diff(y(t), t))+(2*Delta/(1+exp(20*(Pi-t)))+KMIN+Delta)*y(t)+20*Delta*exp(20*(Pi-t))*x(t)/(1+exp(20*(Pi-t)))^2 = 0}

with the following Initial cdts:

ics := {x(0) = 0, y(0) = 0, (D(x))(0) = 0, (D(y))(0) = 0}

How do i draw a graph in the networks package. I have been trying to draw a range of graphs including random graphs but cannot get them to appear in the question.

Thanks

Hi everybody,
I have six coupled PDEs to solve. Because of complexity, Maple can not solve them at once, unless I solve three of them first and then satisfy the boundary conditions, then import them into the remaining equation. So it is somewhat semi-manually. The problem is, I do not know how to extract and modify the answer function from the answer of the PDE. Could you please let me know how I can modify the answer and put it back into the other equations?
Thanx,

Hello, I've been bashing my head against this problem for around 2 hours, looking everywhere to see if I can find a solution in the forums and elsewhere, but I can't. I'd appreciate it if someone could give me some guidance on how to do the following:

Approximate f(x, y) = (y^2) / (x^3) by a polynomial of degree 6 in x - 1 and y + 1.

Hi,

I am a student, Faculty of engineering, computer systems department, my field of study as Theoretical and modeling by using Maple. I have more difficult to solve the system of differential equations . I need any help from you by any way you could suggest. ( you can change the initial conditions to get the primary solution). I try by many methods but i can get any solutions.

dB1(z)/dz= - a.B1(z) – (g/AE). B4(z). B1(z)

dB2(z)/dz= +a.B2(z) + (g/AE). B3(z). B2(z)

Hello,

Is there a command for displaying the name of the actual worksheet file in Maple?

I am looking for a similar command to currentdir(). It displays the actual file path. I would like to get also the file name of my actual worskheet file.

I would like to attach this information to my results automatically.

Thanks for your help in advance.

How do I specify a set number of decimal places after the decimal?

Hi there,

I'm relatively new to Maple and I was wondering how to draw plots using 3DPLOT such that Maple also draws the coordinate-axes (starting at (0,0,0)).

Thanks!

how can i color a plane (for example: z=0.75, or y= 2.5e12, ...) in a 3D plot?

i want to distinguish a plane from other sections of a 3Dplot.
