Hi all,

I am trying to plot multiple ODE plots in Maple 16. I can do them all separately, but cannot figure out how to make to solutions appear in the same plot. I have numeric solutions for sol1 and sol2, and I want to plot A(t), t for each one (together).

Thanks for the help!

I used to work with Matlab and recently I've started to use Maple. In Matlab you can make a function with several commands that does some calculations and calculates one parameter and you can call that function in another function. I need to the same in Maple (i.e. define a function with several commands that calculates a parameter and use the result of that function in another function). Any suggestion?

Hi

How can i convert maple file to matlab ?

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?
