I wasn't given any function or limitation on this, however I just started learning about this(part of my HB after first lesson) and I'd love if someone can show me a simple and effective way to create a vector that looks like 1 1 1 1 1 1 2 2 2 2 2 2

v = [1 1 1 1 1 1 2 2 2 2 2 2]

is there a shorter way? like the way I can write 1:12 and it just writes that?

ceil((1:12)/6)
ans = 1x12
1 1 1 1 1 1 2 2 2 2 2 2

repelem(1:2,6)
ans = 1x12
1 1 1 1 1 1 2 2 2 2 2 2

Hi lior,

Try using the repelem function. This function repeats each element of an input vector a specific number of times. Here's how you can achieve the desired vector:

% Define the elements to repeat

elements = [1 2];

% Define the number of repetitions for each element

repetitions = [6 6];

% Create the vector with repeated elements

result_vector = repelem(elements, repetitions);

% Display the result

disp(result_vector);

So, first define the elements [1 2] that you want to repeat and the number of repetitions [6 6] for each element, use repelem function to generate the vector result_vector with the desired pattern. Finally, use disp to display the result. Please see attached results.

Hope, this answers your question.

An alternative approach —
v = reshape(ones(6,1)*[1 2],1,[])
v = 1x12
1 1 1 1 1 1 2 2 2 2 2 2
