  2. Saying hello with LibraryLink -- Explains how to return a value from a LibraryLink function
  3. Sending greetings from LibraryLink -- Explains how to pass in a value to a LibraryLink function
  4. Squaring integers with LibraryLink -- Explains how to write a basic arithmetic function with LibraryLink
  5. Writing a boolean function with LibraryLink -- Explains how to write a function that returns True or False
  6. Calculating the mean value of a list with LibraryLink -- Explains how to pass lists for a LibraryLink function
  7. Creating a matrix with LibraryLink -- Explains how to return a matrix from a LibraryLink function
  8. Working with complex numbers in LibraryLink 
  9. Working with multiple functions in LibraryLink

Hello Arnoud,

thanks for these very helpful examples. Unfortunately, there is a case missing:

I would like to pass several MTensors as a result via LibraryLink.

Say, I have a real matrix and a list of integers that I want to pass on.

Thanks, Michael

Not sure how to do this off-hand, but I will ask some people who might know.

Another good place to look for a possible answer is the Q&A site called StackExchange:
