Hi! I'm trying to write a for-loop that vary numbers in the following code
z(1,:)=TC_Front_1.signals.values;
z(2,:)=TC_Front_2.signals.values;
z(3,:)=TC_Front_3.signals.values;
z(4,:)=TC_Front_4.signals.values;
...
z(n,:)=TC_Front_n.signals.values;
My questions is:
  1. How do I do when I want to search for the first part 'TC_Front_' so I can se how many there is
  2. How do I write to vary the numbers, like in a for-loop with indexes?

for jj = 1:n
z(jj,:) = eval(['TC_Front_',num2str(jj),'.signals.values']);
end

If the values are coming from a .mat file then use the form of load() that assigns the inputs to a structure; then you can use dynamic field names.
