'How to convert a char array of lines of numbers including '↵' to integers in matlab?

I have variable 'txt' of the type char and I want to turn it into an array of integers:

txt = '-1 1 -3 -1↵ -7 -4 -2 -3 -1 -2↵ -2 -24 -3 -1 -2 -2 -1 -1↵ -3 -1 0 -1 -2 -3 -4 -5↵ -5 -2 -1 -1 -2 -11-15-27↵ -5 -7 -30-19-16-18-19-18↵ -5 -4 -28-28-19-13↵ -4 -3 -13 -6

 '

size(txt)

ans =

 1   160

num2str(txt)

ans =

'-1 1 -3 -1
 -7 -4 -2 -3 -1 -2
 -2 -24 -3 -1 -2 -2 -1 -1
 -3 -1 0 -1 -2 -3 -4 -5
 -5 -2 -1 -1 -2 -11-15-27
 -5 -7 -30-19-16-18-19-18
 -5 -4 -28-28-19-13
 -4 -3 -13 -6
 
 '

str2num(txt)

ans =

 []

double(txt) also return an array of numbers but they are not the same as the number in the txt array. How can I turn txt array into integers?
