Generating bit stream with N samples per bit

I want to generate a bit stream in MATLAB, from the transmitter to pass by the channel

I use MATLAB function "randi" between 0 & 1, so it generates random vectors of 0s & 1s and connects them to produce triangles

I want to make N (e.g N=10) samples per bit, so each bit is produced contains 10 samples, so 1 will be a line not just a point and same as for 0

So, In receiver we works as samples and then take decisions then shifting to work on bits after the sampler (or slicer)

So, How can I do that

I'm not sure, what you are asking for. Maybe you mean:

x = randi([0,1], 1, 5)

x = 1×5

1 0 0 1 0

n = 3;  % Easier to read here. Use 10 in your case.
y = repelem(x, 1, n)

y = 1×15

1 1 1 0 0 0 0 0 0 1 1 1 0 0 0
