Matlab Resample Error

[Jason]

I am trying to downsample a sound file I imported into matlab by using 'resample', however when I try to downsample it I get an error message saying:

??? Undefined function or method 'resample' for input arguments of type 'double'.

I am using a demo version of matlab at the moment (I do own the full version but it is done through a university license and I am having problems connecting to the server) of version R2007a. I have used this command before on matlab on a different computer and it runs fine. Anyone got any idea why I get that error message?

This is exactly what I am inputting and the error message?>> [a, fs, nbits] = >>wavread('Sound.wav');
>> soundsc(a, fs);
>> a2 = resample(a, 16000, 32000);
??? Undefined function or method 'resample' for input arguments of type 'double'.

Thanks.

The RESAMPLE function is part of Signal Processing Toolbox.

Check the output of the VER function to determine if you have this toolbox
installed.
