How to save data coherence in matlab by using fprintf from the given coding?

fs=1000;
xn=importdata('alphaO1.txt');
yn=importdata('deltaCz.txt');
mscohere(xn,yn,[],[],[],fs);

ylim([0 1]);
xlim([0 500]);

[Walter Roberson]

Change

mscohere(xn,yn,[],[],[],fs);

to

cxy = mscohere(xn,yn,[],[],[],fs);

then run the code. When it finishes, tell us what

size(cxy)

shows.
