I discounted a GPValueTable originally, but went back after your post and tried it and seems to do what the OP wants. # import modules import arcpy import numpy as np class Toolbox(object):     def __init__(self):         self.label = "SomeToolbox"         self.alias = "SomeToolbox"         # List of tool classes associated with this toolbox         self.tools = [Tool] class Tool(object):     def __init__(self):         self.label = "SomeTool"         self.description = "SomeTool"         self.canRunInBackground = False     def getParameterInfo(self):         param = arcpy.Parameter(             displayName='The Matrix',             name='TheMatrix',             datatype='GPValueTable',             parameterType="Required",             direction="Input")         param.columns = [['GPString', 'Name'], ['Double', 'BinaYog'], ['Double', 'FiberHat'], ['Double', 'ElektrikHat'], ['Double', 'KaraYolu']]         param.values = [['BinaYog',1,0,0,0],['FiberHat',0,1,0,0],['ElektrikHat',0,0,1,0],['KaraYolu',0,0,0,1]]         return [param]     def execute(self, parameters, messages):         #row[1:] strips off the 1st column         matrix = np.array([row[1:] for row in parameters[0].values],                           dtype=np.float32)         messages.addMessage(matrix) EDIT: added code to show how to turn the Value Table into a numpy array. ...
