Just FYI, I was referring to operator+=(double)  or operator+=(complex),
etc.  (not matrix addition which you can do with Blas_Add_Mult).

I don't remember if I brought this up before, but is there any problem
adding "operator+=" to the matrix/vector classes?

 

They should not use any extra memory, as all the processing is done within
the existing matrices/vectors.

 

Any thoughts?

Done, and committed to CVS.

I tested the gmd one, I'm assuming the others will work, the only difference
is the complex one where it did .r and .i separately (but in the same loop).

Ok, thank you very much.

I agree, the complex case should be fine as well.

By the way, did you think about the work size variable of your 
LaLUInverseIP code?

These are fine and you can add them as you wish. They are quite clear about 
what will happen and which matrices/vectors get modified. (I'm actually 
wondering why I never needed those... whatever. Simply add them.)
