Hi,

I want to use Scid  matrixes for implementing GMM algorithm. I will start by writing Naive Bayes with linear and quadratic decision boundaries .

I reliaze Scid does not provides any functions for getting spesific row or coloumn. Matrixwview class only supplies opIndex function.

Is there anything that I am missing or what is the best to get nth column or row with Scid library.

Link to Scid lib: http://www.kyllingen.net/code/scid/doc/scid_matrix.html

Sad times with linear algebra libraries for me,

Since I can't get  rows and columns easily with Scid, It seems not flexible for me. And also there are other issues for example I can't set matrix to row or column major.

I begin to check alternatives first I begin to investigate Dlib. D lib matrixes are unfortunately static once created their size can't be expanded  and must be square matrix. This restrictions seem too much to me .

The best alternative seems to me scid fork of "Cristi Cobzarenco" link: https://github.com/cristicbz/scid. It has the basic features I need. But it seems last commit made 3 years ago. I couldn't compile it. I am getting error:

scid\internal\regionallocator.d(364): Error: safe function 'scid.internal.region
allocator.threadLocalSegmentSize' cannot call system function 'scid.internal.reg
ionallocator.RegionAllocatorException.this'
Error building library

Any advice about another lib or fix compile error will be welcome.

No idea if it will help with what you need, and the documentation is still a work in progress, but this is my library for embedding D in R (similar to Rcpp):

https://bitbucket.org/bachmeil/dmdinline2/overview

It does have an easy way to work with rows and columns.
