...convert the data vector structure into a matrix structure optimized for nfft

....Copy the data vector structure into an equivalent matrix with nfft column. Thus, the obtained matrix is optimize for the nfft multithreading algorithm use. The middle part is a direct copy of the data vector and we copy on the edges of each column the lambda terms needed to fullfill the correlation of theses data.
