MaplePrimes Questions

Hello, I'm new to Maple.
when I write:


solve({Wa=Ve,-4*Vd+4*Ve=-4*Wa+4*Wb,12*Vc-24*Vd+12*Ve=12*Wa-24*Wb+12*Wc},{Wc});

Maple gives me no output.
Can somebody help me, what I'm doing wrong? (Maple 9.5)
Thank you for your help! 

Hi colleagues. I executed a problem on Maple 12 and the results were on a matrix form as:

A=[11X11 Matrix]

How can i display the full content of the matrix and how can i extract one row or one column from the matrix???

 Hello, everyone,
I have two problems in my worksheet.
First, when I specified the value of "s1" for a smaller number, for example 1e-5 or 1e-6, the imaginary part of "an" tends to infinity or -infinity, however, it should be finite.
Second, the value of "an" is instable when specific value of "s1" is choosen. For example, in the attached worksheet, s1=1.9e-4, the value of "an" will be changed when you click "!!!" button several times(that means execute the entire worksheet).

My contour of integration is a semi circle whose diameter rests on the imaginary axis from -ri to ri.  The arc of radius r is on the positive real axis going from -ri to ri.  On the curve I want to have directional arrows indicating that I am traversing this contour in the positive direction.  How do I create this figure in MAPLE?

my problem is probably that maple assigns everywhere possible the whole expression (cause its analytical)

How do i get it to calculate a float and save it as such?

e.g.

interfaceenergy:=5.

sig:=200.*10^6

Temp:=fsolve(xi_M[Temp,sig,interfaceenergy)=0.5,T, T=100..400])

whattype(Temp) ---> function

...this is part of a nested loop (2) so after some time of calculating maple says

Dear all, 

I have two questions regarding truncated normal distribution.

1. Is there a convenient way in Maple to compute and plot the density function of a truncated normal distribution? I know that in Maple, after creating a random variable, I can use the function Statistics:-PDF to compute the density function, and use DensityPlot to draw the function. But for truncated distribution, I have to compute it manually by doing integration to compute the normalized...

I have a problem.

I solved a problem, but i like to get one solution for one variable.

i send my project.

I am working with two multivariate functions A and B, with coefficients over a finite field. The x-degree of A is greater than or equal to B, which is greater than or equal to 1, and thus I want to find q and r such that:

A = q*B + r, where q, r are elements of K(y,z)[x], where K is my finite field. Obviously, I would like the x-degree of r to be less than that of B, and r not equal to 0.

My problem is this: the Rem and Quo commands, which will deal with my...

Hi,

I have explored some multi-animation with maple, but I can not change the parameters one by one.

Command Explore is analog to Mathematica's Manipulate but the problem in a new worksheet.

How to get Explore like Manipulate in the same worksheet ?

hi, i cant solve the following ODE and Boundary conditions in maple. please help me. i use dsolve and ode analyser but i cant receive and conclusion. thanks.

 

restart:
#beta:=.01;
#lambda:=.3;
s:=f(x)^2*diff(f(x),x,x)+x*f(x)*(1-2*beta)+beta*diff(f(x),x)*(x^2-1);
 
bcs:=f(1)=0,D(f)(-lambda)*f(-lambda)=beta*(lambda^2-1);
     

Dear guys

In my program I have a loop and after some calculation I want to write the results. I use:

" writedata("D:\\arvin\\bao-cmb-h.txt", convert(T, array), float);"

but maple give me an error:

" Error, (in convert/list) object too large "

how can I write my data?

Thanks.



I have a strange error when i try to plot an ODE with "numeric,method=gear,parameters=[...]" as options activated. After this implementation I give the parameter a value: ODE(parameters=[123]); -> works. But when I type "odeplot(ODE, [x(t),y(t)],10..20,numpoints=100);" for example, i get the errormessage:

" Error, (in dsolve/numeric/gear) Array index out of range"

But when i remove the option "method=gear", so that the ODE is solved with default runge-kutta...

I'm developing an application that I'd like to use elements of an array as parameters in MapleSim components - is there a way to use Maple arrays/vectors in MapleSim?

 

Also is there a way to open a file and read its contents (data) as the starting point (parameter set) for a MapleSim simulation?
