Creating a loop for repeated vector values

Hi,

I am attempting to setup a massive vector made up of Current values for a battery model. Before this piece of code I have included, the PosAccelReqCurrent already has 15 values. Is it possible to make a loop to repeat the values below for x amount of times rather than just copy and pasting it x times? It would make my code a lot of more efficient rather than having thousands of lines of the same code.

As further context, this code is to create many repeated current cycles to test battery degredation over time. Apologies if I have not added enough explanation.

Thank you.

%%%%%%%%%%%%%%%
maxPARC = length(PosAccelReqCurrent);
for x=1:6500
    PosAccelReqCurrent(maxPARC+x)=PosAccelReqCurrent(15);
end
for x=1:6500
    ActVel(maxPARC+x)=ActVel(15);
end

maxPARC = length(PosAccelReqCurrent);

for x=1:100
    PosAccelReqCurrent(maxPARC+x)=0;
end
for x=1:100
    ActVel(maxPARC+x)=ActVel(15);
end

maxPARC = length(PosAccelReqCurrent);

for x=1:3470
    PosAccelReqCurrent(maxPARC+x)=15;
end
for x=1:3470
    ActVel(maxPARC+x)=0;
end

No loops necessary.

If those are row vectors, then:

newPARCdata = [PosAccelReqCurrent(15)*ones(1,6500) zeros(1,100) 15*ones(1,3470)];
newAVdata = [ActVel(15)*ones(1,6600) zeros(1,3470)];

PosAccelReqCurrent = [PosAccelReqCurrent repmat(newPARCdata,1,x)];
ActVel = [ActVel repmat(newAVdata,1,x)];

If they are column vectors, then:

newPARCdata = [PosAccelReqCurrent(15)*ones(6500,1); zeros(100,1); 15*ones(3470,1)];
newAVdata = [ActVel(15)*ones(6600,1); zeros(3470,1)];

PosAccelReqCurrent = [PosAccelReqCurrent; repmat(newPARCdata,x,1)];
ActVel = [ActVel; repmat(newAVdata,x,1)];

Here's a way that works whether they are row or column vectors:

newPARCdata = [PosAccelReqCurrent(15)*ones(1,6500) zeros(1,100) 15*ones(1,3470)];
newAVdata = [ActVel(15)*ones(1,6600) zeros(1,3470)];

PosAccelReqCurrent(end+(1:numel(newPARCdata)*x)) = repmat(newPARCdata,1,x);
ActVel(end+(1:numel(newAVdata)*x)) = repmat(newAVdata,1,x);
