When I try to print a 3d figure (actually only this figure) in Matlab as a .eps format, it does not provide a vector graphics rather provides a rasterized figure as my output instead.
This problem is persistent only with this particular figure, rest of them works great (as expected).
This problem replicated in both 2014b, 2015a and 2016b, as these are the only available software versions, I could not test on others. Moreover, if anybody else suffered from this type of problem?
This is the first time I am facing such a problem, as until now I never had any issues with figure printing (both 2d, and 3d).
Kindly do share your suggestions to overcome this problem.

Since the problem is occurring only for this particular case, I request you to use the data file provided in the link, along with this MWE. The problem has also been reported to Mathworks.
The necessary data file E_fw.mat is available in the g-drive link inside the data.zip
To all who guided me here (and who may in the future come across the same issue), I received a reply from Mathworks saying that it indeed automatically switches to rasterization mode (they didn't explain how) when certain conditions are violated (as @AndrasDeak explained). So the way to override is to use -painters extension in the print argument, having the sole disadvantage of the size of the output file blowing up in a nonlinear fashion which explicitly depends on the complexity of the output figure.
I should also say that when the -painters extension is used to override the internal switch, in my case I ended up with having a .eps size of around 450 MB which is actually huge when they have to be reused for documentation purposes.
