MATLAB: Reshape the Matrix to complex number

Question

I have Matrix-like the following

N=64

%X is the complex number % complex number(a+ib) where (a) is real and (ib)is imag number

% I reshap the complex to matrix

X %(64 1) size of matrix = N

real(X); % (64 1)

imag(X); % (64 1)

Xd=[real(X);imag(X)]; %(128 1) = 2N

I want to reshap the matrix to complex as

real+imag

a+ib

return (X) at size (64 1)

thank u

Answer 1

Some methods to get the original (complex) matrix back:

Method one: reshape and matrix multiplication:

Y = reshape(Xd,[],2)*[1;i]

Method two: indexing and complex:

Y = complex(Xd(1:64),Xd(65:128))]

Method three: indexing and addition:

Y = Xd(1:64) + i*Xd(65:128)
