Suppose we have a website:
fullstudy.com/mathematics/mathematics-book.pdf
How can we download this pdf file using urlwrite or websave, using matlab?
Directly downloading this file from the web (without using Matlab) is not an option.

It is only a small number of (100 or so) serialized files.
With the simple urlwrite way, it takes about 5 minutes for a ~20MB pdf file. It is not the issue of their server, because direct download (from web) takes less than 5 seconds for the same file.
Is there any other way to do this which will have a similar timeline (seconds)?
For the serialized version, the exact structure is like this:
fullstudy.com/mathematics_01/mathematics-book_01.pdf
fullstudy.com/mathematics_02/mathematics-book_02.pdf
fullstudy.com/mathematics_04/mathematics-book_04.pdf
and so on, with some entries in between missing.

Why not trying something like FileZilla in this case?
