Hello!!

I have some values in a text file and I just want the values up to the 10000 th position, so I choosed the length, N, 10000. I don't know how to choose the values of EDA just until 10000, because the length (EDA)=14000.

Thank you very much!

data_org = importdata('signal.txt','\t',7); %text file with 7 columms
EDA=data_org.data;
EDA= EDA(:,6); %I only want the values in column 6
N = 10000; 
fs = 1000; 
T=N/fs;
t = (1:N)/fs;
f = (1:N)/T;
plot(t,EDA); %wrong because the length have to be the same

在 MATLAB Online 中打开

N = 10000; 
EDA=data_org.data;
EDA = EDA(1:N,6);
