## Maple Command for μ-recursive function?...

Is there a maple function that implements the semantics of the μ-recursive function (Wikipedia)?

## Connecting oscilloscope with maple 14...

Hey!

I'm really new on using maple 14 and I need help please.

I want to either connect maple 14 software with an oscilloscope for data acquisition or import the data captured by the oscilloscope to maple 14 and manipulate this data with the software for dynamic system analysis so I was wondering if anyone knows a programming code or a command to do this please =( I'm stuck

Thanks for your attention...

## division by zero...

Hi,

I would like to define the following exceptions:

0/0 should be equal with 0, but any other x/0 should be infinity, if x>0 or -infinity, if x<0.

In the following example, I show what I achieved, however, I also would like to have equation (8) to be infinity.

BR,

## Contact Event with MapleSim...

Hello!

I want to make a model with an inner moving circle touching a non-moving, stiff outer circle. 2 differential equations describe the movement of the inner circle, i already have modelled thisand i have the x and y coordinates of the most "exposed point" which will touch the outer circle, as output variables (i could also add the derivatives as output). When the 2 circles touch, i want to "tell" the differential equation model the 2 new derivatives for x and y...

## Error, (in property/ObjProperty) testing against a...

Hello,

I have got a question. I have an Hamiltonianfunctionand want to differentiate this function to all variables. There is no problem with most of the variables, but one doesn't work. The error above occures, when I use the button "execute the entire worksheet". When I just press Enter, the errror does not occure and the right results are presented. But I am not abel to use the results.

Has anyone an idea how I can solve this problem?

## Simple optimization problem...

dear all,

i have a simple optimization problem. the objective function is like A*X + B = E and the constraints are 100 <E < 8000 and 10<X<600. I want to find the Min and Max ranges of A and B such that Amin*Xmin+Bmin=Emin and analogous for maximum. I am not sure about the correctness of my modeling. Please guide me to proceed. Thanks.

I have a nonlinear partial diff eq which I am sure has been categorized.  How do I go about finding literature on the eq & the approach to solve it.  I have visited various websites that have catalogs of nonlinear partial diff eq's.  The problem is notation is so NONSTANDARD I have no IDEA what I am reading.  I have included a PDF eq_of_choice.pdf with my notation which I am familiar with. ...

I'd like to add the summation with just the index below, not the i=1..n form, but Help seems to say that I can only expressions and entities from other palettes...

## Header / Footer date format...

In an erlier post, I referred to the foot date format, and that post didn't trigger a reply, so I imagine that there is no satisfactory answer..

Help states, for FormatTime, "The default format is the ISO 8601 standard default date format..." but the date in the footer is of the style "12/1/10" which has obvious faults. Is there a way to get a decent date format in the footer other than putting it in by hand?

## setoptions3d vs ApplyLinearTransformPlot function....

Visualizing_the_SVD_.mw

Hola ev1:

I like to shorten the size of the command, through setoptions3d function. But it seems that it does not interact with ApplyLinearTransformPlot function.
How to get to label the vectors?
