To fill the value from the variable until the Num counts

Hello everybody,

I would like to make the variable as 'time2' from the 'time' variable.

It fills the value from the time variable until the num counts.

In the case, length(time) is 8 and to make the 30 length of varaible of time as time2,

it will be time(end) + time(end) + time(end) + time....

For it I used several elseif function.

If the num is 100, I need to make more elseif...

Is there a way to make more general for this ?? .....

clc; % Clear the command window.

close all; % Close all figures (except those of imtool.)

clear; % Erase all existing variables. Or clearvars if you want.

time = [5.10616303,9.433357995,13.76055296,18.08774792,23.19391095,29.37822416,35.56253737,40.66870040];

T = length(time);

num = 30;

time2 = zeros(num,1);

for i=1:num

if i <= T

time2(i) = time(i);

elseif i > T && i <= 2*T

time2(i) = time(end) + time(i-T);

elseif i > 2*T && i <= 3*T

time2(i) = time(end) + time(end) + time(i-(2*T));

elseif i > 3*T && i <= 4*T

time2(i) = time(end) + time(end) + time(end) + time(i-(3*T));

end

end

time = [5.10616303,9.433357995,13.76055296,18.08774792,23.19391095,29.37822416,35.56253737,40.66870040];
T = length(time);
num = 30;
time2 = zeros(num,1);

time2(1:T) = time;

nseg = ceil(num/T);  % number of segment of length T
resttime2 = time(:) + (1:nseg-1)*time(end);
resttime2 = resttime2(:);

time2(T+1:end) = resttime2(1:(num-T));

% display the results
reshape(time2, 6, 5)

ans = 6×5
