Yorick is an interpreted programming language designed for numerics, graph plotting, and steering large scientific simulation codes.
It is quite fast due to array syntax, and extensible via C or Fortran routines.
It was created in 1996 by David H. Munro of Lawrence Livermore National Laboratory.
Yorick is good at manipulating elements in N-dimensional arrays conveniently with its powerful syntax.
Several elements can be accessed all at once: Like "theading" in PDL and "broadcasting" in Numpy, Yorick has a mechanism to do this: ".." is a rubber-index to represent zero or more dimensions of the array.
