Description

InputWorkspace

Input

MatrixWorkspace

Mandatory

An input EventWorkspace.

OutputWorkspace

Description

This can also be performed using the Rebin v1 algorithm and having the “PreserveEvents” parameter set to false.

Example - Simple conversion of an EventWorkspace

event_ws = Load('CNCS_7860_event.nxs')
# Run the conversion algorithm
histo_ws = ConvertToMatrixWorkspace(event_ws)
# Check that the original workspace and the converted workspace have the same shape
print("{} {}".format(event_ws.getNumberHistograms(), event_ws.blocksize()))
print("{} {}".format(histo_ws.getNumberHistograms(), histo_ws.blocksize()))
51200 500
51200 500

Example - Conversion when blocksize > 1

event_ws = Load('CNCS_7860_event.nxs')
# Rebin the loaded EventWorkspace to a new EventWorkspace that has > 1 bins
event_ws_rebinned = Rebin(InputWorkspace=event_ws, Params=1e3, PreserveEvents=True)
# Run the conversion algorithm
histo_ws_rebinned = ConvertToMatrixWorkspace(event_ws_rebinned)
# Check that the original workspace and the converted workspace have the same shape
print("{} {}".format(event_ws_rebinned.getNumberHistograms(), event_ws_rebinned.blocksize()))
print("{} {}".format(histo_ws_rebinned.getNumberHistograms(), histo_ws_rebinned.blocksize()))

Output:

51200 17
51200 17
