***This is for encoding of convolutional code***
I have the following vectors, all of them are 1x7 in size
p = 1 0 0 1 1 1 0
q = 1 1 0 1 0 0 1
r = 1 0 1 0 0 1 1
I want to make the following vector 1x7 in size
z = 111 010 001 110 100 101 011
Each element of z is the 3 bits of p,q,r of the same position as a whole bit. If I am not wrong, this is called multiplexing.
Can anyone help how to do it in MATLAB R2021a?
Thank you.

The problem I see is that z cannot be an array of doubles, since 010 and 001 would be just 10 and 1 respectively. You could try and store the bits in a cell array.
clear,clc
p = [1 0 0 1 1 1 0];
q = [1 1 0 1 0 0 1];
r = [1 0 1 0 0 1 1];
z = [p;q;r];
z = mat2cell(z',ones(1,size(z,2)),3)'
z = 1×7 cell array
{[1 1 1]} {[0 1 0]} {[0 0 1]} {[1 1 0]} {[1 0 0]} {[1 0 1]} {[0 1 1]}

In MATLAB binary data is normally stored as character (see BIN2DEC, DEC2BIN, etc.).
Perhaps STRING suits your needs (it gives exactly the size that you request):
p = [1,0,0,1,1,1,0];
q = [1,1,0,1,0,0,1];
r = [1,0,1,0,0,1,1];
s = ""+p+q+r
s = 1×7 string array
"111" "010" "001" "110" "100" "101" "011"
