nelson has failed automated validation.


Requirements represent the minimum quality of a package that is acceptable. When a package version has failed requirements, the package version requires fixing and/or response by the maintainer. Provided a Requirement has flagged correctly, it must be fixed before the package version can be approved. The exact same version should be uploaded during moderation review.

  • Email address should not be used in the Author and Copyright fields of the nuspec file. More...

Guidelines are strong suggestions that improve the quality of a package version. These are considered something to fix for next time to increase the quality of the package. Over time Guidelines can become Requirements. A package version can be approved without addressing Guideline comments but will reduce the quality of the package.

  • Release Notes (releaseNotes) are a short description of changes in each version of a package. Please include releasenotes in the nuspec. NOTE: To prevent the need to continually update this field, providing a URL to an external list of Release Notes is perfectly acceptable. More...
  • Title (title) matches id exactly. Please consider using something slightly more descriptive for the title in the nuspec. More...

We've found nelson v0.6.9.2345 in a submitted status and waiting for your next actions. It has had no updates for 20 or more days since a reviewer has asked for corrections. Please note that if there is no response or fix of the package within 15 days of this message, this package version will automatically be closed (rejected) due to being stale.

Take action:

  • Log in to the site and respond to the review comments.
  • Resubmit fixes for this version.
  • If the package version is failing automated checks, you can self-reject the package.

If your package is failing automated testing, you can use the chocolatey test environment to manually run the verification and determine what may need to be fixed.

Note: We don't like to see packages automatically rejected. It doesn't mean that we don't value your contributions, just that we can not continue to hold packages versions in a waiting status that have possibly been abandoned. If you don't believe you will be able to fix up this version of the package within 15 days, we strongly urge you to log in to the site and respond to the review comments until you are able to.

Unfortunately there has not been progress to move nelson v0.6.9.2345 towards an approved status within 15 days after the last review message, so we need to close (reject) the package version at this time. If you want to pick this version up and move it towards approval in the future, use the contact site admins link on the package page and we can move it back into a submitted status so you can submit updates.

Status Change - Changed status of package from 'submitted' to 'rejected'.


Nelson is an array programming language providing a powerful open computing environment for
engineering and scientific applications using modern C/C++ libraries (Boost, Eigen, …)
and others state of art numerical libraries.

It has sophisticated data structures (including cell, struct, linear systems, …),
an interpreter and a high level programming language.

Nelson has been developed to be an open/modular system where an user can define
these own data types and operations on these data types by using overload.

Nelson environment


  • Types managed by Nelson:

    • double and double complex: scalar, vector, matrix 2D, N dimensions array, sparse matrix.
    • single and single complex: scalar, vector, matrix 2D, N dimensions array, sparse matrix.
    • logical: scalar, vector, matrix 2D, N dimensions array, sparse matrix.
    • character array (UNICODE supported).
    • string array (UNICODE supported).
    • integers 8, 16, 32, 64 signed and unsigned: scalar, vector, matrix 2D, N dimensions array.
    • handle objects.
  • OpenMP and SIMD extensions used.

  • Fast Fourrier Transformation functions based on FFTW and MKL wrapper.

  • SLICOT (Subroutine Library in Systems and Control Theory) interfaces (optional).

  • Message Passing Interface (MPI): functions for parallel computing.

  • JSON decode/encode data support.

  • HDF5 high-level functions I/O,

  • HDF5 used as default data file format (.nh5) load/save workspace,
