I want to get mean ferequncy in rang f = (0.002 0.55) just this . from this code matlab but i get this eror(Array indices must be positive integers or logical values.)
I do not know how to perform my work to solve this problem
my code matlab is:
for i = 1:1
data1 = load(strcat(strcat('park',num2str(i)),'.ts'));
fft1 = fft(data1);
M2 = abs(fft1.^2./length(data1));
f = (0.8167/2)*(0:(length(data1)-1))/length(data1);
figure,hold on;plot(f,M2(:,13),'r','linewidth',1.5);xlim([0.002 0.55]);
% % extract freq feature
% N = mean(M2(0.002 0.55));
end
