Can't plot a surf from MATLAB using pgfplots

Question

for whatever reason I cannot come up with I am not able to plot a surf figure I have generated in MATLAB and then converted to tikz using the script available here. I am getting the following errors:

! Package pgfkeys Error: I do not know the key '/tikz/axis lines' and I am goin g to ignore it. Perhaps you misspelled it.

! Package pgfkeys Error: I do not know the key '/tikz/surf' and I am goin g to ignore it. Perhaps you misspelled it.

! Package pgfkeys Error: I do not know the key '/tikz/colormap/jet' and I am goin g to ignore it. Perhaps you misspelled it.

! Package pgfkeys Error: I do not know the key '/tikz/shader' and I am goin g to ignore it. Perhaps you misspelled it.

I initially thought that it was because of the version I am using of tikz/pgsplots, but I donwloaded the latest versions and I am now using them but still get the same errors...

Funny thing is that other plots that use the same "unknown" tags (i.e: \begin{axis}) work perfectly..

Here is the code I am trying to compile. Any guess?
