Alternative to the function "findpeaks for the Version R2012b

Hi there,

I want to get several maxima and minima from an array. In the ideal case I would also need the position where they are located. The array is quite big (160000 x 1). For this I am looking for an alternative to the function "findpeaks", because I use the Matlab version R2012b without another toolbox.

Thanks
