cprdc(cx1 [, cx2]), cx1 and cx2 REAL matrices representing complex data

Keywords: time series, complex arithmetic
cprdc(cx1, cx2) computes the element wise complex multiplication of
fully complex (pairs of columns constitute real and imaginary parts)
matrices cx1 and cx2.  When cx1 or cx2 has an odd number of columns, it
is augmented with a column of zeros before multiplication.

cprdc(cx) is equivalent to cprdc(cx,cx).

When cx1 or cx2 represents a single complex series (has 1 or 2 columns),
that series is multiplied by all the series in the other arguments.  For
example, when cx1 and cx2 have 2 and 6 columns, respectively, and
nrows(cx1) = nrows(cx2), cprdc(cx1,cx2) is equivalent to
cprdc(cx1[,vector(1,2,1,2,1,2)], cx2).
