Thanks for everyone who replied to my question.
I tried newmat myself, seems to be working well. What I am interested in
is something like
* Fast element-wise operations. You know, it may be slow in R.
* (Some) control over memory allocation. I would like to specify when
the matrix should not be copied.
* Compatibility with R. At least the way how the matrix data is
represented in memory should be the same as R has. Otherwise, the
data interchange may become slow and memory-consuming.
* And, of course, the basic matrix operations like multiplication,
inverting, eigenvalues etc....
I am using linux/gcc if that matters.
Best,
Ott

| What kind of matrix operations do you need?

| Hi folks,
|
| I am planning to write some more time-consuming matrix manipulations in c++.
| What is the experience with the existing c++ matrix libraries? Do you have
| some recommendations? Are some libraries more compatible with R than the
| others?
|
| All suggestions welcome!
