MATLAB (matrix laboratory) is a
multi-paradigm numerical computing
environment and fourth-generation
programming language. Developed by
MathWorks, MATLAB allows matrix manipulations, plotting
of functions and data, implementation of algorithms,
creation of user interfaces, and interfacing with programs
written in other languages†
MATLAB® is a high-level language and interactive
environment for numerical computation, visualization, and
programming. Using MATLAB, you can analyze data,
develop algorithms, and create models and applications‡

LabVIEW (short for Laboratory Virtual Instrument
Engineering Workbench) is a system-design platform
and development environment for a visual
programming language from National Instruments†
LabVIEW is a highly productive development
environment for creating custom applications that
interact with real-world data or signals in fields such as
science and engineering‡
A fun, graphical computer development
environment with emphasis on data processing
and visualization∗
