prefer_zero_one_indexing dissapeared from 2.0 to 2.1: how can I live without it?

[TEJEDA HERNANDEZ, CESAR]

Hello,

 

I have a program that uses that feature, and it seems for me that this feature of doing a Boolean indexing:

 

     given a matrix

 

          a = [1, 2, 3, 4]

 

 

          a ([0, 1, 1, 1])

 

     results in the matrix `[ 2, 3, 4 ]'.

 

But in version 2.1 I can’t find a way to do something similar.

 

¿does any one know?

 

Thanks in advance,

 

César.
