Okay I don't know why, but at some point my document went crazy somehow, so I closed it and when I opened it again it was like this ... the whole document, all what I had made, it was in one single line... =/

Just like this:

Can anyone help? Please... if I copy paste it to like word, I get it all shown, so it IS there..

I am trying to get the output listed into a vector or list, but I am unsuccessful. I get the error code "improper sequence". but the expression works:

N:=24

while N>1 do if evalb(type(N,even)=true) then N:=N/2;print(N);else N:=3*N+1;print(N);end if;end do;

The output generated is:

12

6

10

5

16

8

4

2

I would like to have the output as a list or a vector with two numbers,...

Hi,

I would like to create a 3D plot using plot3d, however the function I'd like to plot is only defined on the integers and the arguments to plot3D define a range of real numbers.

I woul d appreciate any ideas on how to create this plot.

Thanks,

David

I am trying to solve this set of equations ,but i have spent a lot of time rewriting the equations and changing the signs..but i cant get rid of this erroe and solve it for the unknowns.....could anyone tell me what am i doing wrong ?

I made a model in MapleSim, and I want to analysis it in Maple.
But there was an error when I used the 'get equations' buttom.

and my piecewise equation is 

Is there any problem to this equation?
I really didn't know how to solve it.

Hi

I'm trying to use maple to caluclate the product of eight 4x4 matrices. I need to find all the different permutations of these matrices so that means that there are 8!=40320 in total (I am multiplying all the matrices together but in all thier different orders). I can write a simple program with loops to find the products of say three of the matrices but when I try to create a program that calculates the full product of all eight then maple stuggles ...

I have Windows 7 on my laptop.  When I put the Maple disk into my DVD drive, it says the disk is blank.  I took it back to my school and it works fine on their computer.  Any suggestions?

Hi,

I have downloaded the lead acid battery model from the link http://www.maplesoft.com/applications/view.aspx?SID=34125. I have made the whole system as a subsystem block and tried to generate a simulink sfunction block, but I was not successful. I am getting the below error while doing so.

I have a problem understanding how the below reasoning works
for Bruss article “Sum the Odds to One and Stop,”

i) I would like to understand the die problem and more specificaly
why the probability is k(1/6)^1*(5/6)^(k-1). I have a hard time understanding this

ii) How can I apply this reasonong to a coin toss example?

Hi everybody:

I have the following problem. I obtained an asymptotic solution of a hard problem. The final result is a Maple procedure with five arguments; this function has hundred of term and it works beatifully in Maple. However, we need to convert this solution to C or Fortran code and  I am not able to do it.

After the sentence: Fortan(functionname, optimize, output="filename")

I get the following answer

Error, (in PrintTarget) assigning...

I have a worksheet for my students which implements a number of formulas for vector-valued functions such as unit tangent vector and curvature.  All in terms of parameter t. 

Then in some cases we want to evaluate them for a specific value of t.  It works to say t:=2 and then recalculate the expressions.  But after this, what if I want to set t back to no value i.e. make it a variable again?  I have a solution:  delete the line that set...

Hi,

I have a large expression of 10 variables that contains many rational terms. I would like to manipulate it from the form a^2*b^2*c^(-2)*d into for example ((a*b)/c)^2*d. And I want to do this for all terms and combine all variables of power 2.

I know how to do this for arbitrary power a^n/b^n to (a/b)^n but since I have n=2 maple automatically writes (a/b)^2=a^2/b^2 which is what I don't want.

Many thanks 

Hi,

i have a loop as follows

for i from 0 to 10 do
>
> y:= i/2;
>
> f:= 2*x+y;
>
> plot(f,x);
>
> end
> ;

i want each graph with different color depend upon the value of y. in other mean, for each value of y, the color of the graph is defferent. 

could you help me in this problem?

Hello,

my problem is quite complicated, so will try to discribe it shortly.

I am developing a model over 100 periods of time. The value at time t, depends on other values at time t and of the value of the variable itself in the period before (t-1).

For example:

Y_t= K_t^a * L_t^b

K_t= Y_t-1 - C_t-1

C_t-1=C_0 * (1+gC_t-1)^t-1

gC_t-1 depends again on Y_t-1

I have used the FourierTransform command in Maple 14 and I have identified high frequency content in a signal (data collected).

I would like to filter out the high frequency content but I cannot find a command which does that and nor could I find a post about doing so.

There is a package, HarmonicAnalyses, for sale, which I could purchase.

Is there anyway to do this with Maple 14?

Would the Harmonic Analyses package do what I want?
