[math] RealLinearOperator and AbstractRealMatrix

[Sébastien Brisard <se...@m4x.org>]

Hi all,
I've been thinking again about the support for linear operators 
(MATH-581). If RealLinearOperator is ever included into CM, then I think 
AbstractRealMatrix should extend RealLinearOperator. Then, the 
interfaces should be as consistent as possible. That's why I renamed 
some methods
getDomainDimension ---> getColumnDimension
getCodomainDimension ---> getRowDimension
even if "rows" and "columns" are not really meaningful for a matrix-free 
linear operator. I will probably be more understandable this way.
Also, the signature of the default constructor has been changed
was: RealLinearOperator(domainDimension, codomainDimension)
which would translate into: RealLinearOperator(columnDimension, 
rowDimension) ===> INCONSISTENT WITH AbstractRealMatrix
is now: AbstractRealMatrix(rowDimension, columnDimension)

I've attached a new file (#04) to JIRA MATH-581. Unfortunately, I don't 
know how to remove the previous files, so this ticket is getting messy, 
I'm sorry about that.

Hope this new proposition will be agreeable to all.
Sebastien

I'll do that next time. Sorry for the mess for the time being. When we 
get to the "real" stuff (iterative solvers per se), maybe a new ticket 
could be started?

Just attach files with the same name.  Old versions will be visible but
greyed out.
