Julia Intermediate 3: Different Argument Types for Functions

From a channel Lumen includes in full: This is a PhD student's teaching-practice channel made up entirely of structured, numbered programming tutorials in Julia and Fortran, covering basics, MPI, ODE solving, units, debugging and package management. Every available transcript is a hands-on code walkthrough or documentation reading. The only filler is a brief like-and-subscribe line, and the titles are plain and descriptive. The two videos without transcripts carry tutorial titles that clearly sit within the same numbered series.
