My thoughts are that Products should be a module(?), as other
'have products', as opposed to 'are products’?
I'd prefer to make Product an AR::Model. In fact it is a separate
entity with its own behavior and state. It is a core model of your
app, if I understood everything right.
I’m unsure that I even need a Product library (would it just be

|Object-Oriented Programming and databases|
Abstracting your persistence layer (database) is always a good idea.
So, keep your class around!
I would recommend a few things:
Using a using statement only makes sense if you implement IDisposable.
Otherwise; your method is fine.
Don't do direct SELECT statements and the like in your code-behind.
Those should be hidden behind methods in the persistence class.
Otherwise; you are on the righ

Pretty much any built in class that implements the List interface
(e.g. LinkedList or ArrayList can be used to store as much data as the
JVM will allow your program to use. To store these after the program
closes, you'll need a way to store the data in either a file or a
database of some sort, which you can load into a List as needed. As
the List interface includes the contains(Object o) method, a
|Computing an ODE in Matlab|
Please note that matrix exponential is defined for square matrices.
Your attempt to multiply the attenuation coefs with the time vector
doesn't give you what you'd want (which should be a 3D matrix that
should be exponentiated slice by slice).
One of the simple ways would be this:
A = [-2.1, 1.6; -3.1, 2.6];
t = 0:5;
n = numel(t); %'number of samples'
y = NaN(2, n);
y(:,1) = [1;2];
