hprdh()

Usage:
hprdh(hx1 [, hx2]), hx1 and hx2 REAL matrices representing complex data
  with Hermitian symmetry



Keywords: time series, complex arithmetic
                                  Usage
hprdh(hx1, hx2) computes the element-wise complex ratios of elements in
the columns of REAL matrices or vectors hx1 and hx2, considered as
complex matrices in packed Hermitian form.  The result is also a complex
matrix in packed Hermitian form.

Any ratio of the form (0 + 0i)/(0 + 0i) is computed to be 0.

If hx1 or hx2 represents a single complex series (has 1 column), that
series is multiplied by all the series in the other arguments.  For
example, if hx1 is m by 1 and hx2 is m by 3, hprdh(hx1,hx2) is
equivalent to hprdh(hconcat(hx1,hx1,hx1),hx2).

hprdh(hx) is equivalent to hprdh(hx,hx).
