Creating m by m matrix in matlab

[sugaku]

hi all,

i have a vector, z which size is 1 by m.
z = [1 2 3 4 5 6 7 8]

then i want to make a matrix with m by m
Z= [z; z; z; z; z; z; z; z]

if m become bigger i couldn't do it like mentioned above. how could i generate the matrix by a single command?

thank you in advance.

A kind of brute fortish method would be
A=zeros(m)
for r=1:m
A(r,:)=z;
end

I don't know if there's a vectorized way to do it but there probably is

See the repmat() function. For your purpose its repmat(z, size(z)(2), 1)
