Good day,
I have the following cell called "c"
c = {'Conc_510_Y2_Asym_27730_AuditoryOddball'
'Conc_510_Y2_Asym_27730_GoNoGo'
'Conc_510_Y2_Baseline_27855_AuditoryOddball'

'27683_AuditoryOdddball'
'27755_AuditoryOddball'}
I am trying to extract the series of 5 numbers from the cell and store it into an array. Such that the results from the first 5 results would be
[27730;
27730;
27855;
27855;
27632;]
I know that I can use @cellfun to scan if there is a specific number within a cell
find(cell2mat(c)==2)
However, this method won't work here. I would appreciate any guidance/help.
Thanks,

Whatever you posted on some third party website, paste here instead.
To get the results from the k'th cell of the cell array, use braces:
cellContents = c{k}; % Extract k'th cell into double array.

It's not clear exactly what pattern you're looking for. The following will work for your first five numbers:
str2double(regexp(yourcellarray, '\d+(?=[^0-9]*$)', 'match', 'once'))
but so would many other patterns which would produce different results for the rest of the array.
Note: rather than using an external service, paste an excerpt of your cell array into your question.

I removed the pastebin link. This worked perfectly and is just what I needed.
Thank you!
