Matrix Multiplication using Numpy Package

This workflow demonstrates the usage of Python Numpy package for matrix multiplication using Python Script node. The data is read as pandas dataframe and then it is converted into arrays to perform matrix multiplication.

Configure the Python Script node for matrixmultiplicationsThe Python Script node can be provide with a table or an object as inputport and it can output a table, object or an image based on the user'sselection of portsStep 1: Drag the Python Script node to KNIME Analytics PlatformStep 2: Click on the three dots on the node to add an output table portStep 3: Write your script in the "Script" tab and import the numpy package toread data as matrix and perform multiplication. Press "execute script" tocheck if the execution was successful. Adopting Python Bundled Packages : Download and open this workflow to auto-install requirements and execute the Python scripts. This workflow uses a node from KNIMEPython Integration, which installs Python and a number of pre-defined packages on your system. Supported on KNIME Analytics Platform4.7 or higher.
