Hi,
I have around 300 pdf files with 19 pages each. I want to extract from each of them a fraction of a table on page 4 in order to build a research data set. Is i possible to do so using matlab? if so,which toolboxes and functions I need. I have matlab 2013a.

Hi Joseph,
Have you tried using this File Exchange submission?
http://www.mathworks.com/matlabcentral/fileexchange/19798-extract-text-from-a-pdf-document
This seems like the most promising solution. Alternatively, if you could convert the tables to an excel spreadsheet/CSV format, they can then easily be parsed using MATLAB's Excel/CSV functions:

http://www.mathworks.com/help/matlab/ref/csvread.html
I'll let you know if I find any other solutions.
Best,
Kristian

JFTR, since R2017b, extractFileText('filename.pdf','Pages',4) from Text Analytics Toolbox gives you the text on ("physical") page 4 of the PDF, from which you can then extract the parts you need with string operations (extractBetween, regexp, etc.).
