I can only go by Mathematics. In Mathematics, a matrix
is rectangular array. That is what the teacher told us
in class. I also looked up in many other places.

http://www.thefreedictionary.com/matrix

"a. Mathematics A rectangular array of numeric or algebraic
quantities subject to mathematical operations.
b. Something resembling such an array, as in the regular
formation of elements into columns and rows."

http://oxforddictionaries.com/us/definition/american_english/matrix

"3 Mathematics a rectangular array of quantities or
expressions in rows and columns that is treated as a single
entity and manipulated according to particular rules."

http://chortle.ccsu.edu/vectorlessons/vmch13/vmch13_2.html

"A matrix is a collection of numbers arranged into a
fixed number of rows and columns"

http://science.yourdictionary.com/matrix

"Mathematics A rectangular array of numeric or algebraic
quantities subject to mathematical operations."

http://www.macmillandictionary.com/us/dictionary/american/matrix

"math an arrangement of numbers or symbols in a pattern from top to
bottom and from left to right, used for solving problems in mathematics"

http://mathworld.wolfram.com/Matrix.html

"In his 1851 paper, Sylvester wrote, "For this purpose
we must commence, not with a square, but with an oblong
arrangement of terms consisting, suppose, of m lines and
n columns. This will not in itself represent a determinant,
but is, as it were, a Matrix out of which we may form various
systems of determinants by fixing upon a number p, and
selecting at will p lines and p columns, the squares corresponding
of pth order."

https://en.wikipedia.org/wiki/Matrix_%28mathematics%29

"In mathematics, a matrix (plural matrices) is a rectangular
array of numbers, symbols, or expressions, arranged in rows and columns."
