MATLAB: How reapeat a series in a matrix

matrix manipulationsequence

Hi, is one of my first tme that I use matlab. I'd like to know how can do if I have a matrix (6,120) and I want to fill the first row with a sequence of numbers from 1 to 10, that repeats until the end of the row.

Thankyou

YourMatrix = zeros(6,120);
YourMatrix(1,:) = repmat(1:10, 1, 12);

You can use reshape command:

a= [1 2 3 4;5 6 7 8;9 10 11 12; 13 14 15 16]

b = reshape(a,1,16)

or simply

b = a(:)'

Hope it helps!!!

MATLAB: Data every second. want matrix with mean data of every minute.

Use retime and datetime:

a = ones(100, 7);
a(:, 7) = randi(15, 100, 1);
mins = repmat(1:10, 10, 1); a(:, 5) = mins(:);
b = datetime(a(:, 1),a(:, 2),a(:, 3),a(:, 4),a(:, 5),a(:, 6));
value = a(:, 7);
TT1 = timetable(b,value);
newTimes = b(1, :):minutes(1): b(end, :);
TT2 = retime(TT1,newTimes,'mean')
