You mean to replicate them, not multiply them. Multiplication is an arithmetic operation as I recall.

Answer 1

[per isakson]

Try

    x = [1;2;3;4];
    reshape( repmat( transpose(x), [4,1]), [], 1 )

Answer 2

Another way,

x = [1;2;3;4];

result = x( ceil((1:length(x)*4)/4) );

Answer 3

[Matt J]

kron([1;2;3;4], ones(4,1))

Answer 4

[Matt J]

x=1:4;

result=ones(4,1)*x;
result=result(:);
