Find connecting global maxima of a given dataset.

Hi all,

is there any build-in function or toolbox to find the connecting global maxima of a given dataset consiting of xy-values? The maxima should be determined by searching for the first maximum of the dataset and than "going along the x-axis" and determine all following global maxima while neglecting the global maxima found before. From what I understand the "islocalmax" function cannot be manipulated to do so. Do I have to create my own code for this using the max function? What are your recommendations? Exemplarily I illustrated my needs in the attached figure. I case of any further question do not hesitate to ask me :)

Many thanks in advance!

Cheers,

Nico

You can use max right?

Thanks for your answert! Yes, sure! But since I am not only looking for one maximum rather than for the connecting maxima (as illustrated in the attached figure by the red line) one has to write a code for this, isn't it? Or is there a simpler solution? I am only a sporadic MATLAB user and writing a code for this will be quite difficult for me.

Have a look on findpeaks and envelope.

I never worked with these functions before. Could you please specfiy your answer? That would be great! Thanks a lot!
