How to find corresponding indices?

Good Day,

I have a dataset I am working (891 rows,12 columns) with and have already sorted one column with zeros and ones (Logical). I would now like to pull data from 2 other columns (number and text) where the ones are located (neglecting the zeros). How can I write this in matlab?

TIA!

% some data
data = [0 10]+(1:10).'

data = 10×2

1 11 2 12 3 13 4 14 5 15 6 16 7 17 8 18 9 19 10 20

% whether to get each row:
rows_to_get = [false; false; true; true; false; false; false; true; true; false]

rows_to_get = 10×1 logical array
   0
   0
   1
   1
   0
   0
   0
   1
   1
   0

% final result:
result = data(rows_to_get,:)

result = 4×2

3 13 4 14 8 18 9 19
