How to repeat each elements of matrix irregularly

1 visualización (últimos 30 días)
Hello everyone, i have a matrix like:
A =
0.2978 -0.7649 -2.8475 3.4084
And i want to repeat the elements of matrix but differently for each element. For example, i want to repeat 0.2978 two times, -0.7649 three times, -2.8475 two times, and 3.4084 four times. So it will look like:
B =
0.2978 0.2978 -0.7649 -0.7649 -0.7649 -2.8475 -2.8475 3.4084 3.4084 3.4084 3.4084
What is the way to do that? Thank you.

Hi,
This is an easy solution to your exercise. You can adjust it w.r.t your exercise conditions:
A =[0.2978 -0.7649 -2.8475 3.4084];
AA=[];
for ii = 2:numel(A)
AA = [AA, repmat(A(ii-1), 1, ii)];
end
Good luck.

Use repelem():
A =[0.2978 -0.7649 -2.8475 3.4084]
B = repelem(A, [2 : length(A) + 1])

Wow, about time to upgrade. There has been so many improvements in the last 7 years as you can imagine. You can edit the release even after you post you know. I've done it for you this time.
