Depressingly, even in 2014, this view is still extant. Take a look at
the following web pages at Mathworks, which has such wide influence
amongst scientists and engineers:

About Data Types
The term data type refers to the way in which a computer
represents numbers in memory. A data type determines the
amount of storage allocated to a number, the method used to
encode the number's value as a pattern of binary digits, and
the operations available for manipulating the type.

What Is Data Type?
The term data type refers to the way computers represent
numbers in memory. The type determines the amount of storage
allocated to data, the method of encoding a data value as a
pattern of binary digits, and the operations available for
manipulating the data.
(No mention of arrays and matrices as types, even though they are
central to Matlab/Simulink/Stateflow).
