Hello, please help me to vectorize the code below,
%E1 is array
H1=real(E1); %size 144x360
H2=imag(E1); %size 144x360
L=size(array,2); %=360
length=L*2;
T=zeros(size(array,1),length); %size 144x720
M=zeros(size(T)); %size 144x720
h=1:size(array,1); %1:144
for i=0:(L-1)
j=2*i;
T(h,j+1)=H1(h,i+1);
T(h,j+2)=H2(h,i+1);
M(h,j+1)=H2(h,i+1) | H1(h,i+1);
end
Can i vectorized it with bsxfun or arrayfun? Thanks

Just use indexing properly and then this is trivial:
L = size(array,2);
T(:,2:2:2*L) = imag(array);
T(:,1:2:2*L) = real(array);
M(:,1:2:2*L) = T(:,1:2:end) | T(:,2:2:end);
M(:,2*L) = false;
