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

 

Hello i want to solve the differential equation but i have these problem i don't understand  why !?

thanks for your help

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.

 

 

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.

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

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.

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:

    %% Created by Maple 17.01, Windows 7

and the output is:


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

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.

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.

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. 

I want to extract all the symbols and last trade from 

http://finance.yahoo.com/q/cp?s=%5EIXIC

I have tried:

status, data, headers := HTTP:-Get("http://finance.yahoo.com/q/cp?s=%5EIXIC");
data;

but it just gives me a bunch of jiberish! Any ideas?

hi.I want to dsolve set of nonlinear equations with one unknown parameter ...is this possible with dsolve rule.in matlab this possible with bvp4c rule..please help me for this problem.if we should another rule please attached file reform.Thanks alot12.mw

M := 10^2; plot(exp(M), t);

When we execute the above code we get graph in output naturally. But when execute the following code  , there is no graph in output, why?

M := 10^3; plot(exp(M), t);

Thanks in advance for any suggestion.

hi.please help me .why rule ''''Det'''' dose not work properly?

this program attached DET.mwblow.thanks alot
