Rounding Values in Vectors - User Function - Trying to make a function that rounds values in vectors - Сообщения

Version: 0.99 (Build: 7921)
The rounding function concept for a vector seems to work fine, but I am having trouble with a function that works on a vector containing multiple vectors.
Any ideas on how to make this work?

You can use recursive for that.
You have to also check if rounded row is a vector.
It can work with both vector and nested vector.
Here is your code revised.

PS: MarB's solution with Razonar's addition is better actually.
I would use that instead of mine, more elegant.
My version is just a brute algorithm.

Above method will not work if the nested arrays are of different sizes.
Following method will work for any nested array.

Code revised to solve not just vectors but matrices too.
Now very complicated matrices can be rounded.

Great ideas everyone, thanks for the input and improvements.

Good idea to always start code native Smath ... given user extended.

You can also shorten function like this.

Up to this point, proposals round nested vectors.
Dealing with big numbers is also available.

A very short way is to use recursion.
This is just magnificent. Two heads are better than one.
I couldn't hit off how to do it with vectorize.
Kudos

Wonderful!

Brillant solution. Adding eval to the SMath's round enables symbolic evaluations too.
Best regards.
Alvaro.

Minimalistic solution for Maximalists.
Sometimes I really wish I could use Maxima plugin under linux.

It is on my todo list and I think it is possible, but currently priority is on another project which also involves using Maxima and is entirely open source:
