Hi,
let
A= [ 1 10;
2 20;
3 30;
4 40;]
if you want to select data values(2nd column) for time which lies between 1 and 4 in the first column, you can do this:
index1= A(:,1)>1; %gives indexes of all time values with value greater than 1
index2=A(:,1)<4; %gives indexes of all time values with value less than 4
index=index1 & index2 % gives indexes off all time values that lie between 1 and 4
values=A(index, 2) % gives the required data values
% or you can do this in a single line like this
values= A(A(:,1)>1 & A(:,1)<4,2);
Hope this helps.
