Usage of downsample function in 2012b

I am Matlab 2012b installed with 64-bit edition.

I tried using 'downsample' function using a simple vector as an input argument.

It throws following error, "Undefined function 'downsample' for input arguments of type 'double'"

Is it because of 64-bit edition? Because it works perfectly fine on 32-bit edition.

Any suggestions?

Hey I have figured out the problem. It was license issue and I don't have signal processing toolbox installed. :)

Thanks for reply!

Undefined function means that the function does not exist, so parhaps there is a small typo in your call?

Is the signal processing toolbox listed in:

path
on the 64b version?

What happens if you type:

which downsample

?

Yes, I do have signal processing toolbox installed.

which downsample shows the path of function call, downsample.m where it is saved.

[kjetil87]

That is strange, try putting a

which downsample

right before your call in your function/script , does it still list the correct function? (is there a chance that you have redefined it? )
