MATLAB: Saved pdf file doesn’t look like figure

MATLABpdfprintsave2pdf

When I save a figure as a pdf file, the pdf version adds spaces which aren't in the original. The two images attached illustrate the problem. The first image is a screenshot of my matlab figure.
The second image is a screenshot of the pdf version.
As you can see there's a huge gap before the gamma in the title, and also before the exponents in the ylabel for the third subplot. I get exactly the same problem using matlab's print command, i.e.,
print(gcf,'-dpdf',printName)
and using the code save2pdf, which I downloaded from this forum
save2pdf(printName)
Any advice as to how to fix this problem would be most appreciated!
