[ublas] matrix elements as custom types

Hi,

I've looked around at the wiki and previous mailing list posts and I 
cannot find the answer to my question there.  What I need to do is 
define a custom class and set it to be stored in a matrix such as:

matrix<MyCustomClass> mat1(300, 300);

And then it must be able to be multiplied by another matrix of a 
different type.

matrix<MyCustomClass2> mat2(300, 300);

Then I want to be able to take the product of the two matrices have have 
it go into another matrix of a third type:

matrix<MyCustomClass3> mat3(300, 300);

mat3 = prod(mat1, mat2);

Now I have defined operators to multiply MyCustomClass*MyCustomClass2 
and return MyCustomClass3 and also the operator MyCustomClass3 += 
MyCustomClass3

Is there any other operators that I must define for this to compile?  Is 
this even possible with ublas?

Thanks in advance,
-Garret
