For-loop finding the difference between 7 different arrays
显示 更早的评论
Hello,
I am having trouble figuring out how to get one refference array and subtract it versus 7 individual arrays. I have the code below which I can do for one array but I would like to loop it for the 7 arrays, t1-t7
Any help would be much appreciated
A(:,1) = t1(:,1)-tref(:,1); %Measuring the time difference between t1 and tref

You can't loop it since you chose to have separately named 1-D arrays so you can just do it in 7 lines:
A(:,1) = t1(:,1)-tref(:,1); %Measuring the time difference between t1 and tref
A(:,2) = t2(:,1)-tref(:,1); %Measuring the time difference between t2 and tref
A(:,3) = t3(:,1)-tref(:,1); %Measuring the time difference between t3 and tref
A(:,4) = t4(:,1)-tref(:,1); %Measuring the time difference between t4 and tref
A(:,5) = t5(:,1)-tref(:,1); %Measuring the time difference between t5 and tref
A(:,6) = t6(:,1)-tref(:,1); %Measuring the time difference between t6 and tref
A(:,7) = t7(:,1)-tref(:,1); %Measuring the time difference between t7 and tref

Instead of creating separately named arrays, you can create a single array T where you load up each column with the measurements that are now going into the individual vectors. Then you can simply do
A = T - tref;
Actually you don't even need a loop then.
T=cat(3, t1,t2,t3,t4,t5,t6,t7);
A = T-tref;
