Description
Background
Phase 1 of matrix operations was released as part of 1.8
https://github.com/madlib/madlib/blob/v1.8/ReleaseNotes.txt
http://doc.madlib.net/latest/group__grp__matrix.html
This jira for phase 2 is to add additional matrix operations.
Story
Decomposition operations:
– Matrix inverse
matrix_inverse( matrix_in, in_args, matrix_out, out_args)
– Matrix generic inverse
matrix_pinv( matrix_in, in_args, matrix_b, b_args, matrix_out, out_args)
– Matrix eigen extraction
matrix_eigen( matrix_in, in_args, matrix_out)
– Matrix cholesky decomposition
matrix_cholesky( matrix_in, in_args, matrix_out_prefix, out_args)
– Matrix QR decomposition
matrix_qr( matrix_in, in_args, matrix_out_prefix, out_args)
– Matrix LU decomposition
matrix_lu( matrix_in, in_args, matrix_out_prefix, out_args)
– Matrix nuclear norm computing
matrix_nuclear_norm( matrix_in, in_args)
– Matrix rank computing
matrix_rank( matrix_in, in_args)
