Hello, I have a matrix 1000*2 in Excel file. So I call these data and plot them. I am looking for all Maximum and minimum, however I don't know the equation due to having only points. I am using R2012a and couldn't use findpeak. any suggestions please?

If you don't have findpeaks() because you don't have the Signal Processing Toolbox, you can use imregionalmin() and imregionalmax() if you have the Image Processing Toolbox.

Well don't accept the answer if you haven't even tried it. type "ver" on the command line to see what toolboxes you have installed.
