Hi, I want to plot the below data, but only between -10~+10. The raw data is always >-10 to >10. But I only need to plot between -10 &+10. How can I select between -10 ~+10. I also want to get the index of each filtered data between -10~10. Please kindly help. Many many thanks in advance.

idx=M(:,1)<10 & M(:,1)>-10
out=M(idx,:)
plot(out(:,1),out(:,2))
