MATLAB: Array to matrix

array to matrix

Hi all,
I have an array like a:
a=[10 20 30 40];
I want to convert it to the matrix below, without using any for loop just by one command.
b=[ 10 10 20 20 30 30 40 40
10 10 20 20 30 30 40 40
10 10 20 20 30 30 40 40];
How can I do it. Thank you,

Best Answer

  • a = [10 20 30 40];
    b = kron(a,ones(3,2))
