I have an array name time with 1 row and 1000 columns.
time=[5,6,7,2,8,1,3,9......]
I want to call randomly any values from that array. Following is my working algorithm.
time2 = any random values from time
time3 = any random values from time
time4 = (time2 + time3)/2
time5 = any random value from time
common time = 5;
time6 = common time - time5;
time7 = time4 + time6
I have to store the values of time7 and have to repeat this process for 1000 times. That I can get the 1000 times time7 values.
How can I do this in MATLAB?

len = length(time); % length of the vector
time7 = zeros(1,len) ; % initilaize the vector time7 to store your time7
common_time = 5;
for iValue = 1:len
% randi used to get a random value
time2 = time(randi([1, len], 1));
time3 = time(randi([1, len], 1));
time4 = (time2 + time3)/2;
time5 = time(randi([1, len], 1));
time6 = common_time - time5;
time7(iValue) = time4 - time6;
end
