The function `software/pdf_A_chisq_m.m` computes the PDF of
where
according
to the method described in [16]. The syntax is
[lpzH0,ic] = pdf_A_chisq_m(z,A,K,[ic]);

where
`A` is ,
`z` is ,
`K` ia an vector
containing the chi-square parameters ,
and `ic` is an initial condition vector (the saddlepoint location).
Note that the `_m` suffix on the file name is because there exits
an experimental CMEX version `pdf_A_chisq.c`, which is still
slower that the ``.m" version.
