## How to label contours in Maple 17? ...

Asked by:

hi friends

i have a question and i could find the answer in existing questions but it was not clear at all!!!

i want to label my contours and i know that i should use lebelledcontourplot command.

But how?!
i could find an answer:

"1- First download the files located on his webpage.  Advisor6.zip    It should be zipped with 3 files in it.

2 - Unzip them and copy them into a directory which you name, probably somewhere in the maple directory named advisor.  c:\maple12\advisor

3 - Then create a maple.ini in the maple12 directory with the following line to match your directory location
libname:= c:/maple12/advisor, libname:  just like on the instruction installation page."

these are my questions:

1-how can i create a maple.ini?!
2-what should i do with the file i will create?

please explain more about the third phrase and explain exactly what should i do step by step.

thanks a lot

## How to convert vector to matrix? ...

Asked by:

I have a vector of dimension n with each component being an equation of a linear system.

Can maple convert this Vector to a Matrix-Vector form with the matrix being constant coefficients?

into the "Ask a Question" window?

Nothing to add

Actually I want to ask something else.

## How to iterate the wavlet transform?...

Asked by:

Take for instance the signal [1,0,-3,2,1,0,1,2] (considered in Wavelets for Kids, Vidakivic & Mueler, AMS, 1991).

I want to anlalyse it down to the level zero with Haar wavelets. It seems that MAPLE's commnad only applies once.

## Multiple plot with DiscretePlot?...

Asked by:

with(DynamicSystems)

T:= a vector

Iwant to make a single plot of:

DiscretePlot(T,x1,stile=stair); DisdretPlot(T,x2,stile=stair)

The usal way: DiscreePlot(T,[x1,x2]... ain't work

Thansk for helping

## Is there any other way?...

Asked by:

Hello maple experts,

please is there any other way of solving this problem Wht.mw

Some complained that the graphs do not satisfy the boundary conditions smoothly.

Thanks.

## Export as Latex omitting commands...

Asked by:

I have some large worksheets in maple which I would like to export to Latex. Currently, the exported document included both the commands and the results. For example, if the maple code looks like:

The latex document will be:

%% Source Worksheet: test4Export.mw

\end{maplegroup}
\begin{Maple Normal}{

\end{document}

and the output is:

Is there a way to solve this once while exporting in Maple instead of editing the latex code manually?

## What is wrong with my code...

Asked by:

Hello,

the attached code return error for  this values [0, 0.2, 0.4, 0.6] but work perfectly for this [0.2, 0.4, 0.6, 0.8]. I want it to start from 0 value. How do i correct the error? See the worksheet here com.mw

Thanks.

## ImportMatrix and Date...

Asked by:

I have this data I want to import in to Maple.

In Maple I type:

ImportMatrix("C:\\Users\\marc\\Desktop\\data1.csv", delimiter = ",");

then I get the following:

My question now becomes how can I import the data with the correct dates and not just -Aug, 1-Aug etc ?
The method should also work when I have many more columns of dates.

Ps I cant upload the data on MaplePrimes since it is a csv file.

## evaluating forever......

Asked by:

hello people

I have this computation which has to do with my undergraduate project and each time I compute some work (vary parameters), it seems to evaluate forever. although my computer isn't recent and has 2GB of RAM the computation didn't seem to me as much of a task for it. computation works fine with some parameters as 0 but the moment I change it to a natural number, it evaluates forever.

Is there anyway I could speed up computation in maple? or do I just need a faster computer? but I have a dead line for next week. can I upload my worksheet for someone here to help me execute?

thank you in advance.
