Interactive Data Language (IDL) is a high-level language for data manipulation, visualization and analysis. IDL has strong signal and image processing capabilities and extensive math and statistical functions. There is extensive web support with hundreds of freely available applications from a large userbase. IDL includes mapping tools and direct access to standard databases. The IDL development environment requires minimal programming skills.
Simulink is an add-on package for MATLAB that supports simulation and model-based design using a graphical block-programming scheme. An interactive graphical editor is provided for building models and simulations based on an extensive library of customizable program blocks and custom code. A Model Explorer application supports inspection and editing of models, signals, parameters and generated code.
