Hello,

I have a little question about the property "local" or not of a index in a for loop.

I notice that when I make "for loop" the index i is not local. In the small example, when I ask to evaluate i after having done this loop, the answer is 5 and not i.

Example :

for i from 1 to 4 do
i^2
od;

i; --> 5

How can I do to ask Maple to use index as local ?

Thanks a lot for your help.

 

Hello,

After trigonometric manipulations in a mechanical problem, I can obtain the desired angles but defined with modulo 2Pi.

I would like to program or find a function which can do this operation :

While angle doesn't belong to [-Pi, Pi]

do 

  If angle > Pi then do angle = angle - 2Pi

  If angle < - Pi then do angle = angle + 2Pi

end

Is there an existing function which can do this operation ?

Otherwise, may you help me to program it ?

Thanks a lot for your help

Hello,

How can I do to suppress all the complex components of a vector ? Is there a simple code to do this?

For example, I would like to replace the complex components with zero.

If the considered vector is a:= [2+I,2,5], i would like to obtain after modifications amod:= [0,2,5] ou amod  [Nothing,2,5]

Nota :

The origin of my issue is to be able to plot points with the following syntax :

pointplot([tp,xp,symbol = solidcircle,color=black,symbolsize = 10): where xp is a vector with, sometimes, some complex components. 

I would like to plot the points only for the real components of xp

Thanks a lot for your help

 

 

Hello,

I would like to obtain the display of several outputs from a procedure.

Sorry for this question which should be quiet simple but I didn't manage to solve my issue. By the past, I always wanted to obtain only one output from a procedure.

I put attached a example of procedure which calculates x^2 and x^3 for a given value of x.

With my procedure, I didn't obtain the display of the output calculating the square value.

How can I display all the outputs of a procedure ?

Thank you for your help

Hello,

I have .mla. package and I would like to create the source code associated to this package.

In the past, you have also help me to obtain the source code of procedure of the module.

Here the post where Carl Love has helped me :

http://www.mapleprimes.com/questions/203676-Open-A-Maple-Package

How can I do to create the complete source code of package directly ?

Is there a direct way enabling to not have to read one procedure by one procedure but to obtain the code source for all the package ?

Thank you for your help
