repeat an array (a signal) over a specific period

4 views (last 30 days)
Dear community,
I have the following values:
  • phi_card is an array 20001x1 double
  • phi is 1x100 double, that starts on -3.14 and ends on +3.14.
which can be shown in the following screenshot image:
The goal is to extend the (red) signal as long as the (blue) signal. My first guess is to do a for loop as follows:
for i=1:length(phi_card)
...
end
but then my low skills of programming in matlab gets me struggle how to continue. How would you do it? Can you help me?
Thank you,
David

changed the factor to 2000, as the array phi_card is actually 200001x1, but yes, you solved it pretty simple. Thank you :)
