Examples

This file contains a short information on each example, so that you can get a first impression even without LabVIEW on your computer.

01a_add_two_numbers.vi

• Adding two numbers and getting result back
• Demonstrates all the basics needed: Starting and stopping Julia server and ZMQ communication, encoding, sending, receiving, and decoding data using JSON-encoding
• Wiring diagram (screenshot)
• Front panel
• Accompanying Julia script

01b_add_two_numbers.vi

• Adding two numbers and getting result back
• Demonstrate slightly different way to get data encoded
• Wiring diagram
• Front panel
• Julia script: see 01a

02-sqrt_with_error_processing.vi

• Square root
• Demonstrate error processing
• Wiring diagram
• Front panel
• Accompanying Julia script

03-without_args_and_returned_val.vi

• Printing "Hello World" in the Julia terminal window
• Wiring diagram
• Front panel
• Accompanying Julia script

04-nested_data_structures.vi

• Somewhat more complex data structures with JSON-encoding
• Wiring diagram
• Front panel
• Accompanying Julia script

05a-multiple_functions.vi

• Access to multiple Julia-implemented functions
• Wiring diagram
• Front panel
• Accompanying Julia script

05b-multiple_functions.vi

• The same, but getting the list of available function from the server
• Wiring diagram
• Front panel
• Julia script: see 05a

05c-multifunc_external-server.vi

• The same, but Julia server started externally (and can be on a different computer)
• Wiring diagram
• Front panel
• Accompanying Julia script

06a-arrays.vi

• Let Julia solve a system of linear equations, invert a matrix, and compute determinant. For this purpose send and receive a 2D and an 1D array.
• Demonstrate flattening and unflattening of numeric arrays to/from a binary format. JSON-encoded data are sent and received here, too.
• Wiring diagram
• Front panel
• Accompanying Julia script

06b-arrays.vi

• Solving a system of linear equations with random generated arrays of an arbitrary size (within reasonable). Comparing LabVIEW and Julia computation time.
• Wiring diagram
• Front panel
• Julia script: see 06a

06c-arrays.vi

• Demonstrate concurrent access to Julia server: Solving a system of equations in one loop, and computing eigenvalues in a separate one.
• Wiring diagram
• Front panel
• Julia script: see 06a

07-get-and_display_image.vi

• Get a test image from Julia
• Demonstrate sending an image from Julia in binary format and unflattening it on LabVIEW.
• Wiring diagram
• Front panel
• Accompanying Julia script

Note: Julia script needs some additional packages, it is better to install them manually before actually running the test (see the script)

08-send-and-receive-img.vi

• Wiring diagram
• Front panel
• Accompanying Julia script

After studying the above examples you should be able to use this package for your purposes.

For the examples 09 and 10 - you may try them after installing the package on your computer.
