How to write the string after a spesific point in cell array?

Hello,

Lets say I have a text file and it contains

ASDASDDSA 123213213 ASDADASDA 18128, ASDSAD [ 123 123 123 12 3 123123 123 123]

I want to take the [ 123 123 123 12 3 123123 123 123] part of this cell array. How can I do that? Its like find([) and a = array(55:end, 1)

Thank you

You say that you have a text file (please upload a sample file by clicking the paperclip button) but then the rest of your question talks about a cell array (which you do not describe). Unclear.

"I want to take the [ 123 123 123 12 3 123123 123 123] "

As text, or do you actually want the numeric values?

s = 'ASDASDDSA 123213213 ASDADASDA 18128, ASDSAD [ 123 123 123 12 3 123123 123 123]'

s = 'ASDASDDSA 123213213 ASDADASDA 18128, ASDSAD [ 123 123 123 12 3 123123 123 123]'

t = regexp(s, '\[[\d\s]*\]', 'match')

t = 1×1 cell array
    {'[ 123 123 123 12 3 123123 123 123]'}
