There is a way to import a PDF as image in MATLAB by making use of the Apache PDFBox library that we ship. Please see the following post for the code:

I'm also searching for this since an hour now. So far I cound not find any solution to this. The link suggested above is a dead end, even 5 years later.

I considered ImageMagick command line but I could not even get that one to work, I'm a noob when it comes to mingw and cygwin...

"So far I cound not find any solution to this."

Did you try extractfiletext as mizuki suggested?

There is no general solution to extracting data from a PDF. The link clearly explains why.

"The link suggested above is a dead end, even 5 years later."

In fact using PDFs is a dead-end. They are not a data-exchange format. You might have some luck with OCR.
