Thanks a lot again;
I will look at the views and see how that works out. The matrix size is not
modified inside of a layer but the content only (gradient) while the
optimizer outside of the instances modifies the weight matrix accoding to
gradients.
Storing all layers gradients and weights at one

Thank you Dirk for the quick response;
and for noting the memory handling.
I am aware of it and there are other ways of obtaining a pointer to some
memory location. I used malloc/free to put focus on arma::mat copying data
during assignment and/or not able to use reference as class member.

Steven,
In a case like this I would try to set up a fist minimal working example
using just plain C++, and no R. Once that works, try it with R.
For Armadillo, the docs at http://arma.sourceforge.net/docs.html#Mat are your
best shot. I presume you saw what it says about strict=true. Also, in
Hello,
I am having trouble creating arma::mat with external writeable auxiliary
memory as class member;
ie:
struct Example {
Example( double *ptr ){
// . see provided minimal working example
}
arma::mat ExtPtr; // this is what I would like to have
}
What is it that I am doing wron
