cmplx(Re,Im), Re and Im REAL matrices with same size and shape.

Keywords: time series, complex arithmetic
cmplx(re,im) combines matrices re and im considered as the real and
imaginary parts of a complex matrix. The j-th columns of re and im
become the 2j-1-th and 2j-th columns of the result.  Re and im must have
the same size and shape and the output has the same number of rows and
twice the columns.  For example, if re and im are both 5 by 2,
cmplx(re,im) is equivalent to hconcat(re[,1],im[,1],re[,2],im[,2]).

cmplx(re) is equivalent to cmplx(re,0*re), that is, it produces a
complex matrix with 0 imaginary part.
