function [M_real] = C2R_vector(M_complex)
%Transforms the k^th column of matrix M_complex to the k^th column of
%matrix M_real applying the  c->[real(c) imag(c)] transformation ([x1 + i * y1;...;xD + i * yD] -> [x1;y1;...;xD;yD]) coordinate-wise. This function is the inverse of 'R2C_vector.m'.
%
%INPUT:
%  M_complex: DxT sized complex matrix.
%OUTPUT:
%  M_real: (2D)xT size real matrix.
