How to call the post processing data(in matlab environment) from a particular coordinate?

Hai all,
I have a 3D geometry and I run the Transient Heat Transfer Finite element problem in the comsol GUI environment. Also I did some post processing in GUI environment. I then save the file as .m file and opened it in matlab.
I want to call the temperature solution at a coordinate point in matlab interface. I am struggling to find out the function to do this.
Can anybody help me to find out the function that give me the time temperature history matrix?

Hi
In v 3.5 I suppose you want to use the posteval or postinterp (evaluate or interpolate postprocessing, but for the exact calling sequence I have to rebuild them each time from the doc, slightly complex, as there are many options.
Good luck
Ivar

Thank you Ivar...
I tried to use this function..Not get any luck ..can you please elaborate this little more?
I saw the syntax for this. In that the variable v1,v 2 etc will give the temp time value right? But what we will give as input to this function like e1, e2, etc? What this means? From the help I think we have to enter some function or something in this field rt? I only want to call a variable that includes the time temperature values of a particular problem.
Thank you once again

Hai all,
I got the solution. The syntax I used is Y=real(postinterp(xfem,'T',[x;y;z],'solnum','all'));
This will give the Y matrix with time temperature history at point(x,y,z). .
thanks to comsol support
