How to compute frequency and amplitude from a text file?

So far, i have used this code to plot the text file:
[fid,msg] = fopen('Rose.txt','rt');
assert(fid>=3,msg)
C = textscan(fid, '%f%f', 'CommentStyle','#', 'CollectOutput',true);
fclose(fid);
M = C{1};
After this i wish to calculate frequency and amplitude for a duration of 5 seconds at different intervals. Can someone please help me out with the code in order to do so? Thanks in advance :)

Does your data have some kind of time based oscillation? If so then you can use an FFT tool. As for sampling frequency, there should be some way of finding out, but you can always just pick something and get relative results based on the frequency you picked.
Yes, the link is still useful.
