I would like to understand this code which has been discussed in the forum a moment ago.

Here the Maple code :

Does somebody know the theoric developpements to this code ?

May you help me to add comments so as to facilitate the link with the theory ? One line in front of each procedure should be enough for me to understand. For the moment, I didn't manage to match it with the theory.

When I would understand this code, I would like in a second step compare the result with Catmull-Rom splines.

Thanks a lot for your help.

 @acer : I think this subject may interest you



Is it possible to obtain a nice indentation with a automatic process? Do you have some tips on this subject?

My objective is to improve the indentation of my code so as to make my worksheet easier to read.

Thank you for your help.


Thanks to different posts of the subject "Exporting data from Excel to Maple", I could learn the method to do it and conduct it.

Now, I would like to store the data exported from Excel to Maple in the worksheet and make my worksheet independent from the excel sheet.

The idea is that I can send my worksheet to a collegue and he can use without the excel sheet.

May you advice me a strategy to store the imported data ?

The copy/ paste works but it doesn't look smart.

Thank you for your help.



I would like to build a periodic curve but starting from a parametric curve and not with a function.

Thanks to you tips, I could obtain a periodic function with a piecewise function starting from a function (

I would like to do the same approach but starting from this parametric curve f :

f:=unapply(V, t);
plot( [f(t)[1],f(t)[2], t = 0..evalf(Pi)],color=red, scaling=constrained);

And I would like to build a periodic curve (the period is defined on the x axis) g such as :


Unfortunately, the approach presented in the post does'nt work anymore.

Do you have ideas to build this periodic curve starting from the parametric curve defined above ?

The aim of my question is more linked to the methodolody than the result.

Thank you for your help.


I would like to build a periodic function based on the function x-->x².

For x belonging to [0,2], the function is defined like this :


And for the rest of the domain in R, the function should be periodic with a period of 2.

In other words, I would like to define a function which permits me to obtain this plot :


Sorry, for my picture which is very ugly, but it should enable to explain what I'm looking for.

1) Is a new piecewise function based on f function is the better solution to create this kind of periodic function ?

2) I didn't find or understand with the help how i can create "infinite" piecewise function. May you help me to define this kind of piecewise function ?

Thanks a lot for your help.

P.S: With the term "nested" in my title I only want to say that I want to apply another piecewise function (for example g) on a already created function (for example f). this term may be not very appropriated.
