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

Usage
hdivhj(hx1, hx2) computes the element-wise complex ratio of elements
in the columns of hx1 and hconj(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 returned as 0 + 0i. The ratio
of a non-zero element of cx1 and 0 + 0i is MISSING + MISSING*i.
When hx1 represents a single complex series (has 1 column), that series
is divided by all the complex conjugates of the series in hx2.
Similarly, when hx2 represents a single complex series, all the series in
hx1 are divided by hconj(hx1).
For example, if hx1 is m by 1 and hx2 is m by 3, hdivhj(hx1,hx2) is
equivalent to hdivhj(hconcat(hx1,hx1,hx1),hx2).
hdivhj(hx) is equivalent to hdivhj(hx,hx).
