Matlab - building a matrix by merging the same raw vector multiple times

Question

Is there a matlab function which allows me to do the following operation?

x = [1 2 2 3];

and then based on x I want to build the ma

Answer 1

You could try using vertcat, like this:

x = [1 2 2 3];
m = vertcat(x,x,x,x);

Or even simply:

x = [1 2 2 3];
m = [x;x;x;x];

EDIT:

for multiples of x, you can do:

x = [1 2 2 3];
m = [x;2*x;3*x];  %  [1 2 2 3; 2 4 4 6; 3 6 6 9]

EDIT2:

For an arbitrary number of x's in m...

n = 3; % number of repetitions...
x = [1 2 2 3];
m = [];
for i=1:n
    m = [m;x];
end
