Hi,
I was considering jumping into the JDKRandomGenerator exception discussion, but
I did not want to hijack it.
Not sure if any of you have had a chance to looks at this:
https://github.com/firefly-math/firefly-math-exceptions/
https://github.com/firefly-math/firefly-math-exceptions/blob/maste
Should look like this, with some typos fixed:
/**
...
* @throws MatrixDimensionMismatchException if the dimensions of
* {@code destination} do not match those of {@code this}.
* @throws NumberIsTooSmallException if {@code endRow < startRow} or
* {@code endColumn < startCo

One of the point in having exceptions that extends our own root
exception is that users at higher level can catch this top level.
Currently, we don't even advertise properly what we throw. We even
miss to forward upward some exceptions thrown at low level in the
javadoc/signature of out upper

Looks good. Where is the code? ;-)
So CM clients would:
catch(MathException e) {
String exceptionTemplate = ResourceBundle.getBundle("cm.exception.templates", new
Locale("en", "US")).getString(e.getType());
String i18Nmessage = buildMessage(exceptionTemplate, e.getContext());
[...]

A few drawbacks to having IAE thrown by CM is that it complicates and blurres
things for those designing a handler that catches all CM exceptions. CM
advertising a factory that throws each exception 'type' under globally unique
conditions minimizes root cause analysis time and indirection.

Hola,
I started working on my LevenbergMarquardt optimizer experiment, and figured
I'd share the Lombok generated immutable configuration class that I split off
from the optimizer. This is only for show...Not trying to restart the lombok

Hi Gilles,
It sounds like we're starting to coalesce on this. Hopefully this is not going
to come as too much of a shock :). [1] The exception patch will permeate
every class that throws an exception. We will have to delete all the other
exception and replace them with MathException. Here
So if IUC whenever we are dealing with matrices, a MDME should be thrown? So
in this needs an update?:

Actually - I the Factory is used, then the key signature should determine if
it's an MDME or DME. So if 4 keys are used row, column, row, column then MDME
otherwise DME...Sound good?

In RealVector there is an isInfinite() method that checks for isInfinite() and
isNan() at the same time. If any coordinate is infinite, it will return
true...unless a value is Nan...then it will return false. I'm probably missing
something...but it seems like isInfinite() should return true i

Hi,
What do you think of removing iterator(), Entry, and Iterator() from
RealVector? ArrayRealVector can replace these with Vector...I think...Still
need to attempt it. Vector is synchronized so it makes it easier to make
ArrayRealVector thread safe.
Cheers,
Ole

Hi,
Just thought I'd share a concrete callback interface that I think this may work
well for optimizers in general, even though I'm just working on Levenberg
Marquardt ATM. The interface is pasted below, but roughly here's how it works.

Hi,
In RealMatrixFormat.parse() MatrixUtils makes the decision on what type of
RealMatrix instance to return. Flexibility is gained if it just returns
double[][] letting the caller decide what type of RealMatrix instance to
create. It's also better for modularity, as is reduces RealMatrixFor
