assigning of multiple arrays

I have 5 different arrays of same size. How can i optimize this? Something like rhoo = thetaa = thetaa1 = thetaa2 = zeros(ss2,121).

[ss1, ss2] = size(0:1:38);
zitaa = ones(ss2,121);
rhoo = zeros(ss2,121);
thetaa = zeros(ss2,121);
thetaa1 = zeros(ss2,121);
thetaa2 = zeros(ss2,121);

Read about deal.

[ss1, ss2] = size(0:1:38);
zitaa = ones(ss2,121);
[rhoo,thetaa,thetaa1,thetaa2] = deal(zeros(ss2,121)) ;
