Unzipping a gzipped string

Hello, Currently, we are using PHP to read data from a gzipped, base 64 encoded database and outputting the results which is then read by Matlab and manipulated as needed.
I would like to read the database directly from Matlab. I have no problem reading the database and decoding from Base64. However, I cannot understand how to unzip (uncompress) the string.
In PHP, it is a simple function called 'gzuncompress'. However, in Matlab, the gzip function requires a file, not a string.
Any suggestions would be great. Thanks Keith

You could always call a PHP script from Matlab using the system() call and have it return the uncompressed string.

Yes, there are several functions in matlab that are severely limited compared to other languages as they only work on files and not on streams / strings. Other than Jose-Luis' answer, you can
- save your string to a file and use matlab gunzip. That's not going to be fast
- use java.util.zip.GZIPInputStream. May be a bit awkward. Certainly not a one-liner.
