OutputWorkspace	Output	MatrixWorkspace	Mandatory	The name to give the output workspace

Description

An Algorithm designed to allow for the TableWorkspace output of the PlotPeakByLogValue algorithm to be transformed into a Matrix workspace based on the desired parameters.

Usage

Example - ProcessIndirectFitParameters

# Create a host workspace
tws = WorkspaceFactory.createTable()
tws.addColumn("double", "A")
tws.addColumn("double", "B")
tws.addColumn("double", "B_Err")
tws.addColumn("double", "D")
tws.addRow([1,2,3,4])
tws.addRow([5,6,7,8])
tws.addRow([9,0,1,2])
tws.addRow([0,0,0,1])

# Add to Mantid Workspace list
mtd.addOrReplace("TableWs",tws)
wsName = "outputWorkspace"

# "D" is not included in the algorithm params list
ProcessIndirectFitParameters(tws, 'A', "B", OutputWorkspace=wsName)

wsOut = mtd[wsName]

# Print the result
print("{} is a {} and the Y values are:".format(wsOut, wsOut.id()))
print(wsOut.readY(0))

Output:

outputWorkspace is a Workspace2D and the Y values are:
    [ 2.  6.  0.  0.]
