Jed,

•         A’x=b, where A’=[A^-1 U B]=
What does the notation above mean?

ü  That means A’ consists A^-1 and B.  A’ is a sparse matrix at the order of 2 million.  B = sparse matrix at the order of 2 million to be mixed and mingled with A^-1.
What are the dimensions and sparsity of each piece.

ü  The dimension of A^-1 is about 225,000.  B is about 2 millions.


If you have an "inverse" floating around, what sort of operator is it the inverse of.

ü  A is a double complex matrix we have generated from a practical application using FEM.
