Force a workspace to be a histogram

Description

Since most of the math operations (+-*/) are implemented for an event workspace, it would be useful to have an algorithm that converts an event workspace into a workspace2d (losing the events). Currently the rebin algorithm does this if the input and output workspace names are different, but it would be useful for something to do it in-place without having to carry around the binning parameters separately. This will become increasingly important as instruments with larger event lists (NOMAD, EQSANS, ...) start using mantid. It is already an issue for batch processing POWGEN data.

A solution for the time being is the CloneWorkspace algorithm. For as long as this remains Event-unaware it will do what you want.

Decided to create a new algorithm called ConvertToMatrxWorkspace() that will basically be a copy of CloneWorkspace() so we will not get bitten when CloneWorkspace() changes and becomes event aware.

(In [8021]) Initial version that is a copy of CloneWorkspace(). refs #2021

  • Status changed from accepted to verify
  • Resolution set to fixed

(In [8022]) Initial unit test - clone of CloneWorkspaceTest() for now. fixes #2021

This works as advertised.
