Have a good day. I am trying to find an easy way of writing a loop below:
v=rand(100,3)
for iz=1:3
for iznext=1 expv(:,iz)=v(:,iz)*Q_z(iz,iznext)+v(:,iz)*Q_z(iz,iznext+1)+v(:,iz)*Q_z(iz,iznext+2);
end
end
Thanks in advance.

vec = ones(1,5)*Q_z.' ;
exp2(1:100,:) = vec ;

Thanks but i need to use v_e in the form. v_e will not be ones(100,5) later on. it is just an initial guess. I will keep iterate that.
