Hi everyone,

Is it possible to create a continuous time wiener process in Maple?

When we create a wiener process and then a sample path, the values of the sample path are saved in a table, so if I call W(1.5) there is no answer.

How can this be solved?

Thanks.

Hi,

I'm writting because I don't know how to solve this problem. I look for it in the web, but I don't

find the solution.

I have a vector with 4 variables, for example:

[54*a +3*b -c +d, 32*a -c +d, 96*b -69*c +85*d, 6*a + 9*b+3*c+9*d]

In really there is 4 equations. And I need to solve with other vector like:

[0,0,0,0]

I don't know the commands for do this... I search it in internet but I don't find anything.

Below we have approximations involving the MRB constant. The MRB constant plus a fraction is saved as P while a combination of another constant is saved as Q. We then subtract Q from P and always have a very small result!

Is there a possibility in Maple to define a set of elements using a rule or semanticdescription. The problem is that  I need to define a set of numbers of the concrete form (e.g. of the form a+b\sqrt[3](2)). Or more complecated task: the set of pairs (a,b) where a,b::integer. And then I need to define an abstract operation on that set. I explain: my global task is to create a procedure to define whether a set with an operation is a group (where a set is defined using a rule).

u''-w^2+Eu^2=0,           u(0)=A,  u'(0)=0

How can I solve this question the variational iteration method with maple.please help me!

hi

I have 10 equations and the summation of them will give me the answer but each of them have small numeric noises and the sumation of them makes the final result inaccurate.  For example the first equation is 

I have an equation that is a function of two variables i.e Cp(beta,lambda). I have to plot several Cp curves on the same graph for a range of lambda=0..15 (x-axis). The 1st curve I want Cp@beta=0, 2nd curve Cp@beta=5, 3rdcurve Cp@beta=10 .... and so on

How can I do this without having to define a separate Cp equation for each beta value?

Hi！

I get the result which was stored in table, such as:

m:=table([1=[151，153，155，160]，2=[157，152，153，150]，3=[161，158，152，156]])

I can't export it to excel, because the type of m is table, the export  instruction must be array or matrix.

Please help me, Thank you!

When I use the command 'ImportMatrix', this error occourred. And I could assure that the filename and directory are true.

The file is just a simple matrix in 3 dimensions. It contains seven lines and three rows. The screenshort is just as follows. 

And I want to know what's the error. 

Thank you!

Let say that you have two matricies:

X := Matrix(Statistics[Shuffle]([seq(x[i], i = 1 .. 100)]));
Y := Matrix(Statistics[Shuffle]([seq(y[i], i = 1 .. 100)]));

For example the matrix x could be:    x[45]    x[12]     x[2]     x[10]      etc
For example the matrix y could be:    x[12]    x[1]       x[20...

Hello

I have Problem with the Maple command plotsetup, it does not seem to work within an if-statement.

What i would like to do is this:

1. Make a matrix with 0 or 1 as enteries

2. convert this matrix into a list where the 1's are points. (So the Matrix entery Matrix[1][1]:=1 would give the listvector:=[1,1]

3. plot these vectors as graphs and store them with the help of plotsetup

4. changing the matrix and rinse and repet 2,3,4 until satisfied

Hi,

i have to make an iteration in the following way, but i have a problem to plot the result. Has someone an idea how to plot?

s_1 := 0.779e-1*t^2-.1345*t+.2031:
s_2 := 1.3502*t-6.8742:
s_3 := .1112*t^2-1.5108*t+11.527:
s_4 := 1.9322*t-15.099:
s_5 := -0.178e-1*t^2+2.648*t-22.312:
V_0 := .3*.15:
p_0 := 100000:

t:= 0:
tmp:= p_0:
S := 0:

while t do

if t >= 0 and t if t > 9.5 and t if t > 12.875...

Dear Primers

I have an integral equation of the form below:

;

In this equation, u0,u1, s1, s2 are konwn constants and f(y) is a function with a certain exact form. I want to get the analytical solution

Hello,

I have a very important question that I can't seem to find anywhere in the literature.  I am trying to create a procedure to do something that would be seeminly impossible by hand.  In doing so, I need to create exactly 729 variables, which I would like to simply call x_i for i=1...729.  Yet the problem is that I don't know how to define the variable x_i during the procedure.  For example, I would like to do something of the sort:

Hi all,

I am trying to implement boundary conditions in MAPLE, but I don't know how to implement them,  I am attaching a maple file for your kind comments.  An example of similar kind will be of real help.

Thanks in advance
