Data Matrix from CiMatrix is a 2-D matrix code designed to pack a lot of information in a very small space. A Data Matrix symbol can store between one and 500 characters. The symbol is also scalable between a 1-mil square to a 14-inch square. That means that a Data Matrix symbol has a maximum theoretical density of 500 million characters to the inch! The practical density will, of course, be limited by the resolution of the printing and reading technology used.
table or matrix of scores in which persons, subjects, or cases are listed in rows of the table and the information collected on each subject is listed along the columns of the table (Shavelson, 1996)
T the public domain code from RVSI Acuity CiMatrix, is a 2D matrix symbology designed to pack a lot of information into a very small space. The Data Matrix symbology employs Reed-Solomon error correction with data redundancy to guarantee a fast and accurate read.
a rectangle of responses with rows (or columns) defined by objects and columns (or rows) defined by agents.
Variable size two dimensional matrix symbology that is inherently omnidirectional. Data Matrix has a high degree error correction capability and is used primarily for part marking and tracking.
the rectangular arrangement of the raw data on n cases over m variables. The most common data matrix is defined with rows for the cases and columns for the variables, and a factor analysis is performed to reduce the dimensionality of the columns (variables). This standard data matrix can be transposed for cluster analysis or Q factor analysis where the intent of the analysis is to reduce the dimensionality of the cases dimension.
