Re: [eigen] Matrix assignment

[ Thread Index | Date Index | More Archives ]

Not a big issue from my point of view: I hate the implicit operator= anyway! Whenever I use an operator= I define it explictly. That might be just me but I find implicit operator= too slippery.

Well, I found a drawback of operator= not making implicit resize:

a class with Eigen matrices as members does not have a well working
implicit operator= function...

For me is ok, I'll just have to implement an explicit operator= or forbid it.

hm... resizeAssign sounds a bit weird to me. Perhaps with only one
additional letter:


that can be interpreted as a shortcut for m0.resized().assign(m1);.
Or, something much shorter and almost as explicit (IMO):


I think it is quite clear that a "set" operation is allowed to resize
the destination, isn't it ? another argument: when we allow the
destination to be resized, that mean we are re-initializing the
matrix, so "set" makes sense.
