repeat an array (a signal) over a specific period

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

new_phi=repmat(phi,1,200)

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