Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	TableWorkspace	Mandatory	An input TableWorkspace.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	An output Workspace2D.
ColumnX	Input	string	Mandatory	The column name for the X vector.
ColumnY	Input	string	Mandatory	The column name for the Y vector.
ColumnE	Input	string		The column name for the E vector (optional).

Description

Creates a single spectrum Workspace2D with X,Y, and E copied from columns ColumnX, ColumnY, and ColumnE respectively. If ColumnE is not set the E vector will be filled with 1s. The type of the columns must be convertible to C++ double.

Usage

Example

t=WorkspaceFactory.createTable()
t.addColumn("double","A")
t.addColumn("double","B")
t.addColumn("double","BError")
t.addRow([1,2,1])
t.addRow([3,4,1])
t.addRow([5,6,1])

#add it to the Mantid workspace list
mtd.addOrReplace("myTable",t)

ws=ConvertTableToMatrixWorkspace(t,"A","B","BError")

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

Output:

ws is a Workspace2D and the Y values are:
[ 2.  4.  6.]
