8. Overview of LabVIEW
• LabVIEW – Laboratory Virtual Instrument Engineering Workbench
• Graphical programming language that allows for instrument control,
data acquisition, and pre/post processing of acquired data.
9. Graphical programming language & Data flow
• LabVIEW relies on graphical symbols rather than textual language to
describe programming actions.
• The principle of dataflow, in which functions execute only after receivi
ng the necessary data, governs execution in a straightforward manner.
11. How does LabVIEW work?
• LabVIEW programs are called:
Virtual Instruments (VIs)
because their appearance and operation imitate actual instruments.
• However, they are analogous to main programs, functions and subroutines
from popular language like C, Fortran, Pascal, …

15. LabVIEW Vs Matlab
• MATLAB is much better for computation than LabVIEW, mostly because classical program
code is much more appropriate for calculations than block diagrams.
• Chart shows that the functions for classical engineering calculations (Bode, FFT) are very well
optimized in LabVIEW and faster than in MATLAB.
• The biggest advantage of LabVIEW is fast and simple construction of the graphical user
interface that facilitates the updating of parameters (no need to interfere with the code) and e
legant presentation of the results.
• Another advantage of LabVIEW is that most MATLAB functions are accessible from LabVIEW
via the MathScript Node, which can actually pass data to m code, execute it and get results
back.
