I am wondering if there is a way to do so...
Suppose I have a 1 x 5 matrix that contains 5 random numbers, x=[2,10,31,24,11]
Now, I would like to make it become y=[2,3,10,11,31,32,24,25,11,12]
that is, add a column next to each column in z, and each of the additional column added carries the value that is +1 of z's value.

y = reshape( [x; x+1], [], 1);

Not so sophisticated, but intuitively clear way:
y = repelem(x,2);
y(2:2:end) = y(2:2:end)+1;
