Summary
MEM0 was developed by Dr. Nailong Wu while a visiting scientist at
NOAO. It
has been tested on several platforms and is believed to be stable.
Should
you find any problems or have questions please contact Dr. Nailong
Wu via
email at nailong@stsci.edu.
This is a task for 1-D or 2-D image restoration by MEM. In search
of the
maximum point of the objective function, the approximate
Newton-Raphson method
for optimization is used. Data fit and the total power are
controlled by the
Lagrange multipliers \fIalpha\fR and \fIbeta\fR, respectively, to
meet the
constraints. (See REFERENCES.)
The program uses a double iteration scheme: the values of
\fIalpha\fR and
\fIbeta\fR are changed in the outer iteration, while the inner
iteration
is for finding the ME solution for the particular \fIalpha\fR and
\fIbeta\fR.
