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?

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:

PageSize: [47×4 double]
PDFVersion: "1.6"
Title: ""

This is possible on R2023a or b
If you do not have R2023b use MATLAB online
