Summary

Multiply a MDHistoWorkspace by another one or a scalar.

Properties

Name Direction Type Default Description
LHSWorkspace Input IMDWorkspace Mandatory An MDEventWorkspace, MDHistoWorkspace or WorkspaceSingleValue as the left-hand side of the operation.
RHSWorkspace Input IMDWorkspace Mandatory An MDEventWorkspace, MDHistoWorkspace or WorkspaceSingleValue as the right-hand side of the operation.
OutputWorkspace Output IMDWorkspace Mandatory Name of the output MDEventWorkspace or MDHistoWorkspace.

Description

Multiply two MDHistoWorkspace’s or a MDHistoWorkspace and a scalar.

The error of \(f = a * b\) is propagated with \(df^2 = f^2 * (da^2 / a^2 + db^2 / b^2)\)

  • MDHistoWorkspace * MDHistoWorkspace
    • The operation is performed element-by-element.
  • MDHistoWorkspace * Scalar or Scalar * MDHistoWorkspace
    • Every element of the MDHistoWorkspace is multiplied by the scalar.
  • :ref:`MDEventWorkspace <MDWorkspace>`’s
    • This operation is not supported, as it is not clear what its meaning would be.
