Where is findepeaks function?

Hi, I read about findpeaks() function. I'm looking for this version: findpeaks(name,'threshold',nr). There is no function like this in may Matlab. I cannot find code or file. Where can I find it? Sorry for my English and thanks in advance for any help.

It's in the Signal Processing Toolbox. If you get an error that means that you don't have the toolbox.

Can I download this toolbox? Where can I find it?

Otherwise, as Image Analyst pointed out, there are plenty of tools on FEX, e.g.

See the Signal Processing Toolbox: http://www.mathworks.com/help/signal/ref/findpeaks.html

Go here: MATLAB Contact Us and ask for a 30 day free trial.

If you don't want that, there are plenty of look-alikes in the file Exchange.
