Reduced D matrix #50

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Optimize storage of D matrix to use less memory (at least in sequential mode).

A lot of ideas can be taken from OpenDDA code (and corresponding thesis & 
paper). 

One particular idea of symmetry with respect to changes in order of axes and 
their signs, can be implemented based on current code for '-int so' and '-int 
fcd_so'. In other words, existing redundancy is exemplified by the optimized 
storage of tables.

In previous comment '-int fcd_so' should be replaced by '-int igt_so'.

Such optimizations will also accelerate the calculation of D matrix, that is 
also important, e.g. for '-int igt'.

The improvement can be made similar to current implementation of tables of 
Sommerfeld integrals.
