Hello, I have curiosity for the use of this symbol in brackets: [~].
For example, I've seen it, calling a function: [~]=function(S).
Where get stored this symbol, what it contents, and why is it used?
Thanks a lot!

Example
x=[2 1 3 0 5]
[val,idx]=sort(x)
The result
val =
0 1 2 3 5
idx =
4 2 1 3 5
If we want to get just idx
[~,idx]= sort(x)
the result is
idx =
4 2 1 3 5

There is no equivalent in Python. Python cannot return to multiple variables.
You need to design each Python function to return an Object (equivalent to MATLAB struct), or a tuple (which is immutable), or a list.
Whatever you decide, you could put None into the first output location. However, there still needs to be something there to receive the entire set of outputs and pull out the remaining wanted values.
