scatter polar plot interpolation

How can I produce a scatter plot in polar coordinates in Matlab? I need to have a scatter plot (r,theta,Z) where Z values are represented with a colorbar.
The result which I would like to obtain is the same of polarPlot function in R (openair package). In the image you can see an example of graph obtained
with R.
In Matlab I tried with ScatterWindRose (from File Exchange) function, but it is not exactly what I want. I need a kind of surface interpolation of the dots.
Can you help me?

Have a look at the help for TriScatteredInterp, griddata those functions should help you interpolate between your measurement points, then you might have use for this file exchange contribution: Polar pcolor

Try to find out why! Step 1, go trhough all possible permutations of Z R and theta.
Step 2: type "dbstop if error" on the command-line prompt, run the polarPcolor again - and you'll get a debug-prompt in the function where the error occurred, then you have command-line access to all variables in that workspace - as well as the possibility to jump further up (and down) the function-call-stack by "dbup" (and dbdown).
