LabView gets more VIs and math

EDITORS' CHOICE
LabView Version 7.1 adds additional Express virtual instruments (VIs), more math, and more real-time development applications over version 7. Express VIs, which shorten the language's learning curve, let you develop applications without writing LabView code—LabView will generate the code for you.
The NI-Scope Express VI acquires data from one of three NI high-speed digitizers. You can create your own oscilloscope, spectrum analyzer, or transient recorder from this VI. NI-FGEN lets you build your own function generator with standard waveforms such as sine and square waves while NI-FGEN (Arb) lets you create an arbitrary waveform generator. NI-HSDIO (Input) and NI-HSDIO (Output) let you create VIs for generating and reading digital patterns on NI's high-speed digital I/O cards.
LabView 7.1 adds 50 math functions over previous versions. Functions include linear algebra, eigenvalues and eigenvectors, partial fractions, and polynomial evaluation.
A LabView 7.1 real-time module works with NI-DAQmx data-acquisition drivers and lets you use the driver in real-time applications. An execution-trace toolkit lets you visually debug real-time code with nanosecond precision.
