I have a very long string value, approx. 13,000 characters long, that is made up of the letters X, Y and Z. So:
sub = 'XYZYXYZYZYZXYZYXYZ....'
and so on. Within the long string, there is also every so often a 0:
sub = '...X0Y...'
The 0 represents a break point. I need to write out this long sequence onto a single txt file, but at each instance where there is a '0', I need to remove that zero and start a new line on the text file.
How would I go about doing this?

Ran in:
sub = 'XYZYXYZYZYZXYZYXYZ0XYXYXYX';
tmp = split(sub,'0');
fprintf('%s\n',tmp{:})
XYZYXYZYZYZXYZYXYZ XYXYXYX

Ran in:
sub = 'XYZYXYZYZYZXYZYXYZ0XYXYXYX';
sub2 = replace(sub, '0', newline)
sub2 =
'XYZYXYZYZYZXYZYXYZ XYXYXYX'
