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.]
