Step matrix where each value is repeated

1) I want to create a 1xN matrix where it increases in steps however each step is repeated x amount of times e.g. [0 0 0 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5].

In my specific case it will start at 0 go up in steps of 250 and finish at 8000 but each value should be repeated 33 times.

2) I have a matrix that goes up in steps e.g [2 4 6 8], I want a new 1XN matrix that does the same steps but repeats X amount of times e.g [2 4 6 8 2 4 6 8 2 4 6 8...]

In my specific case it will start at 0 go up in steps of 800 until 8000 then go back to 0 and repeat 33 times.

Thanks in advance :)

Use the repelem function (introduced in R2015a).

actually sorry I have got this to work for scenario 1 but not 2

As always, my pleasure!

For the vector, the related function repmat is easier:

v2 = [2 4 6 8];
v2r = repmat(v2, 1, 3);

Here it repeats three times.

I’m not certain what to do with this:

‘In my specific case it will start at 0 go up in steps of 800 until 8000 then go back to 0 and repeat 33 times.’

however the repmat function could be appropriate here as well.
