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.

Can someone help me to generate the same, identical grpah over several periods in x-axis? In exact term, I mean that I need to plot a periodical grpah, that repeats itself over the interval? It is like given a periodical function and now have to draw it many times...(function can be any form, not only sine and cosine)
 

Could i manually reset status bar (i.e. memory and time values)? restart; doesn't help.

I put Celsius in my equation and I get the wrong answer even though I've loaded the Units Package:

I have to put in the conversion to Kelvin by myself to get the right answer:

What am I doing wrong?

Thanks ahead of time!

Hi simulators

Is there an easy way to give a global time frame/limits for all plots: typically I need to simulate a few seconds to get rid of all my transients, and then I would like to zoom in on the effect of interest. Now I have only found out how to reset one by one each graph via the axis properties, I have a dozen graphs per simulation 4 variables to scan over ten points each, that makes a damn lot of graphs properties click to reset, results: I need 60 sec to...

Hello

I wanted to vary my mass item in MapleSim5, to have it appear and dissapear. I noted I could us the variable "1*t" [kg] in a rigid body mass item, that worked out fine

Then I wanted to have a force variable depending on the time, but now I get a message Main.t is not defined in Main

So finally how to refer correctly to the "time" ?

Subdiary question: how to use signal blocks to generate a named variable that I use elswhere in my model for a Parameter input

I've noticed times are off in mapleprimes. 

For example, Foreign exchange post I replied to (yesterday morning? I'm sure it was, it was not last evening).  However this morning 7:58 am Sept 29 the post I replied with says I replied Yesterday at 8:45pm (something is amiss with am's and pm's or something)

hi all,

To create an observability grammian I have to integrate a matrix with some equations that are difficult to integrate due to multiple time dependent variables. The simplest expression in the matrix is:

z₁^2 * sin( z₅ * t)^2          (1)

where z1 and z5 are from a state space model with 5 states and are given by:

z₁dot = z_{2     ...}

Time and time again you get caught up working with Maple and before you know it your 20 minutes of alloted time has turned into almost 1 hour.

Here's a little procedure alarm message to remind you it's time to start shutting down.  Start this procedure in a seperate worksheet and enter the number of minutes before you want your Maple alarm message popping up.  Open a new worksheet and start your work.  When the time is up, your message will pop up unless...

I have a mapleTA question that blocks students from starting a mastery assignment until I tell them how to do the problem. But some students are gaming it but finding out the problem from an earlier section. I want to game back by making the answer change depending on the wall clock, that is the section they are in. To do so, I need a clock function to tell the time. Since I can call maple inside mapleTA, a maple solution will also work.

Hello!

I am rather new to maple and have a few questions considering one of my programs.

1. In my program I use 9 nested for loops. Despite trying to figure something out, I couldnt come up with a way of using less for loops.

2. In some of the for loops I want to start the loop from a variable of the for loop above it. Maple doesnt seem to be very happy about this.

3. I want to make a list of all the results produced by the for loops. However...

I would like to ask a 2-part question in Maple TA in which the correct response to the second part of the question is based on the student's response to the first part of the question.

Here is a simple example.

Question #1

A) What is 1+4 ?

B) What is 2 times your solution to part A?

Obviously, the correct answer to B is 10, but what if the student thought that the correct answer to A was 4? Then if they put 8 as the answer to B I would...

Hey guys, 

Its my first post, so please be lenient. I have done an internship at a theoretical physics department and part of my work was to plot a particular only numerically solvable integral over time (problem from Quantum Mechanics). I wrote a maple code and made it work, but it only produces results for certain values and even for those it takes more than one hour to plot one graph. Since this is my first big project written in maple, i assume, that the code...

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 thoght of...

Dear All,

I am not an expert in Mapple, also my calculus courses were quite long ago. I would like to compare different decision methods. The simpler ones worked with the code below (even if it was slow). but I have problems with the differentiation and the integration of two complex methods (i.e., dia and topsis).

All these methods can be described in general with the  following function:

f:= (X::Matrix,C::Vector)-> TerminalScores::Vector
