scatteredInterpolant function missing?!?! HELP!

Ok, I have a giant code, but I know this section is not working for me.

scatteredInterpolant(x,y,PRESS)

All of these are matrices 13x1 (for testing purposes).

I am getting back this error and have tried finding the function path but function is not found I guess.

HELP!!!

scatteredInterpolant requires R2013a or later. You are probably trying to use a release older than that. If so then see if you have TriScatteredInterp; if not then let us know which release you are using.

Ohhh, that's probably it then. I'm using MATLAB_R2011b on my macbook. It my work on my desktop machine at the office then.... Thanks.

Try scatteredInterpolant([x y],PRESS)

x,y, PRESS should be column vectors of same length.

[Navier_Stroke]

Yes, they are the same length. But this does not work. I get the same error... that the scatteredInterpolant is an undefined function for input arguments of type double.

Then version problem..as Walter answered.
