How to repeat a column several times?

Consider this scenario -

a =[1;2.3;3.2;4.5;5.7];
b=[a,a,a,a,a];

Is there a better way to do this?

repmat()

b = repmat(a,5)

DHRUVINKUMAR, repmat(a,5) will repeat in both dimensions. Correct is

b = repmat(a,1,5)

Ameer Hamza, Oh sorry. You are right Ameer. Thanks for it.
