I would save your data to a vector, then add the random numbers afterwards:

T = 1:60;                               % Original Vector (Created)
Tm = reshape(T(:), 5, []);              % Create Matrix From Column Vector
p = randi([-2 2], 1, size(Tm,2));       % Generate Random Numbers
Tm = [Tm; p];                           % Add Random Numbers To Matrix
T = reshape(Tm, [], 1);                 % Regenerate Column Vector

star thanks for the solution but star i have required only p values and addition of all p values

My pleasure.

The p values are computed separately, so you can add them using the sum function.

Do you want 5 simulated seconds (that might take only a fraction of a second to simulate), or do you want to have MATLAB wait doing nothing for those five seconds?

Have a look at creating a timer object. See overview here
