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.
