Interpreted language is a programming language in which programs are 'indirectly' executed by an interpreter program. This can be contrasted with a compiled language which is converted into machine code and then 'directly' executed by the host CPU...
A programming language is an artificial language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely....
Numerics is typically the term used to describe the numerical field of employment, or its instructional program at a college or university . Numerics occupations can include sub-divisions such as tooling specialist, materials specialist, and others.-Numerical programming:Also known as numerical...
In mathematics, the graph of a function f is the collection of all ordered pairs . In particular, if x is a real number, graph means the graphical representation of this collection, in the form of a curve on a Cartesian plane, together with Cartesian axes, etc. Graphing on a Cartesian plane is...
plotting and steering large scientific simulation codes. It is quite fast due to array syntax, and extensible via C
C (programming language)
C is a general-purpose computer programming language developed between 1969 and 1973 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system....
David Herbert Munro is a physicist at Lawrence Livermore National Laboratory who created the programming language Yorick as well as the scientific graphics library Gist. Munro earned his B.S. at Caltech and Ph.D. at the Massachusetts Institute of Technology...

Features
Indexing
Yorick is good at manipulating elements in N-dimensional arrays conveniently with its powerful syntax.
PDL is a set of array programming extensions to the Perl programming language.PDL is an extension to Perl v5, intended for scientific and other data intensive programming tasks...
(Perl Data Language) and "broadcasting" in Numpy (Numeric extension for Python), Yorick has a mechanism to do this:
> x=[1,2,3]
> x
[1,2,3]
> y=1,2,3],[4,5,6
> y
1,2,3],[4,5,6
> y(-,)
[1],[2],[3,4],[5],[6]
> x(-,)
1],[2],[3
> x
1,2,3
> x/y
1,1,1],[0,0,0
> y=1.,2,3],[4,5,6
> x/y
1,1,1],[0.25,0.4,0.5
Rubber index
".." is a rubber-index to represent zero or more dimensions of the array.
Tensors are geometric objects that describe linear relations between vectors, scalars, and other tensors. Elementary examples include the dot product, the cross product, and linear maps. Vectors and scalars themselves are also tensors. A tensor can be represented as a multi-dimensional array of...
