Dear all,

I created a 3x1 struct using folling code

data_alone_paired(1,1).name = 'pair#1_paired';

data_alone_paired(2,1).name = 'pair#2_paired';

data_alone_paired(3,1).name = 'pair#3_paired';

Subsequently, I filled the struct with data using acceleration data from motion analysis

Pair#1

data_alone_paired(1,1).acc_pelvis_subject1 = data_alone(1).fsignal_down(:,2);

data_alone_paired(1,1).acc_pelvis_subject2 = data_alone(2).fsignal_down(:,1);

Pair#2

data_alone_paired(2,1).acc_pelvis_subject1 = data_alone(3).fsignal_down(:,1);

data_alone_paired(2,1).acc_pelvis_subject2 = data_alone(4).fsignal_down(:,2);

Pair#3

data_alone_paired(3,1).acc_pelvis_subject1 = data_alone(5).fsignal_down(:,2);

data_alone_paired(3,1).acc_pelvis_subject2 = data_alone(6).fsignal_down(:,1);

Any suggestions how to automate this code using a loop?

Regards and thank you very much for your help.

Jonas

There are typos in your code. Presumably, you really meant,

% Pair#1
data_alone_paired(1,1).acc_pelvis_subject1 = data_alone(1).fsignal_down(:,1);
data_alone_paired(1,1).acc_pelvis_subject2 = data_alone(2).fsignal_down(:,2);
% Pair#2
data_alone_paired(2,1).acc_pelvis_subject1 = data_alone(3).fsignal_down(:,1);
data_alone_paired(2,1).acc_pelvis_subject2 = data_alone(4).fsignal_down(:,2);
% Pair#3
data_alone_paired(3,1).acc_pelvis_subject1 = data_alone(5).fsignal_down(:,1);
data_alone_paired(3,1).acc_pelvis_subject2 = data_alone(6).fsignal_down(:,2);

Dear Matt,

thank you very much for your response. It was no typo. But your corretion makes it much more easier.

for i=1:3
data_alone_paired(i,1).acc_pelvis_subject1 = data_alone(2*i-1).fsignal_down(:,1);
data_alone_paired(i,1).acc_pelvis_subject2 = data_alone(2*i).fsignal_down(:,2);
end
