Hay, you might want to elaborate what ket and bra are for the non informed.

Like this?
ket0 = [1; 0; 0];
ket1 = [0; 1; 0];
ket2 = [0; 0; 1];
bra0 = [1 0 0];
bra1 = [0 1 0];
bra2 = [0 0 1];
Ans = ket0*bra0 + ket1*bra1 + ket2*bra2;
Else you would need to elaborate on your problem so we can understand better, what you intend to do

Bra and Ket are only alternative notations for vectors, so a bra is a row vector and ket is a culomn vector. I have had lectures in quantum mechanics, so bras and kets are not unknown to me, just what you want to do with them in matlab does not become clear in your question.
Could you write more than just one sentence on the matter amd deliver a full description of what your problem is and what you want to achieve?

Ok, Matlab has no notation for bra and ket. You can define vectors (as nx1 or 1xn Arrays) and then do standard vector operation on those.
