How to find out number of pages in a PDF file?

I use the matlab function extractFileText( ) (from the Text Analytics Toolbox) to read PDF file.

But how do I find out number of pages in a PDF file?

pdfinfo returns this information, starting in 23a.

I don't know of anything built into MATLAB that would provide this. It's possible you could write a batch file/shell script to do this for you using an external tool like pdftk, ghostscript, or qpdf.

filename = "file_Name.pdf";

info = pdfinfo(filename)

info = struct with fields:

NumPages: 5

PageSize: [47×4 double]

PDFVersion: "1.6"

Title: ""

Subject: ""

Language: "en-GB"

Keywords: ""

Author: "William Shakespeare"

Creator: "Microsoft® Word 2013"

This is possible on R2023a or b

If you do not have R2023b use MATLAB online
