Hello Everyone,
I want to extract the first the maximas in my graph and save the sequence in a seperate variable. I know the maximum function gives me the maximum value in a data set. But I am not able to use this information for finding the next peaks. I have uploaded the graph on the following link and I will mark the peaks which I want to extract from this.

Try using findpeaks() in the Signal Processing Toolbox or imregionalmax() in the Image Processing Toolbox.

You can use a cell array to store variable-sized information, so row 1 could have 9 peaks, row 2 could have 5 peaks, and row 3 can have 11 peaks, etc. See the FAQ for a discussion of cell arrays:
