can you tell me what is the use of Pack Data IP --> Pack vector and how is it working?

FOllwing is the Matlab Function code under Pack Vector, I want to understand it and what acctually it is doing?

function y = pack_vector(u)

%#codegen

assert(isreal(u),'Expected input to be real');

N = coder.const(numel(u));

temp = coder.nullcopy((cast_to_fi(zeros([N 1],'like',u))));

% Interleave real/imag

coder.unroll();

for ii=N:-1:1

temp(N-ii+1) = u(ii);

end

y = bitconcat(temp);

I believe this code uses bitconcat to concatenate all the elements of the vector into a single unsigned value.

u(1) becomes the MSB, while u(4) is the LSB (this is as a result of how the for loop index is used toa ccess the values of u into temp).
