I am trying to vectorize this code.. what can be the vectorization of this code with input data
function hat_y=omp(s,T,N)
Size=size(T);
M=Size(1);
hat_y=zeros(1,N);
Aug_t=[];
r_n=s;
for times=1:M;
for col=1:N;
product(col)=abs(T(:,col)'*r_n);
end
[val,pos]=max(product);
Aug_t=[Aug_t,T(:,pos)];
T(:,pos)=zeros(M,1);
aug_y=(Aug_t'*Aug_t)^(-1)*Aug_t'*s;
r_n=s-Aug_t*aug_y;
pos_array(times)=pos;
if (abs(aug_y(end))^2/norm(aug_y)<0.05)
break;
end
end
hat_y(pos_array)=aug_y;
