Hi guys, I have a multiple rows of strings and I want get words that contains "#" all in a single column.
Example:
data = {'he is #coming #today'; 'will #it rain?'};
The desired output:
out = {'#coming';
'#today';
'#it'}
Thanks

You forgot the quotes or double quotes. It matters if "strings" means cell strings or the modern string class. Please edit the question and post valid Matlab syntax.

Perhaps these are cell strings:
data = {'he is #coming #today'; 'will #it rain?'};
words = strsplit(sprintf('%s ', data{:}), ' ').';
hasHash = ~cellfun('isempty', strfind(words, '#'));
result = words(hasHash);
There are many other ways. Does the # appear anywhere in the word? The example looks like it is the first character in all cases. Then:
data = {'he is #coming #today'; 'will #it rain?'};
words = strsplit(sprintf('%s ', data{:}), ' ').';
result = words(strncmp(words, '#', 1));
Or:
results = setdiff(words, strrep(words, '#', '*')).'

Using a regular expression is trivially easy:
>> data = {'he is #coming #today'; 'will #it rain?'};
>> C = regexpi(data,'#[a-z]+','match');
>> [C{:}]
ans =
'#coming' '#today' '#it'
