b) The fact that the derived work is not the original OpenMath

both this document and the derived work are Content Dictionaries
then the derived work must include a different CDName element,
chosen so that it cannot be confused with any works adopted by
the OpenMath Society.  In particular, if there is a Content
Dictionary Group whose name is, for example, `math' containing
Content Dictionaries named `math1', `math2' etc., then you should
not name a derived Content Dictionary `mathN' where N is an integer.
However you are free to name it `private_mathN' or some such.  This
is because the names `mathN' may be used by the OpenMath Society
for future extensions.

intact.  The simplest way to do this is to distribute the derived
work under the OpenMath license, but this is not a requirement.

This CD treats matrices and vectors in a row oriented fashion (using matrixrow's).

## vector

Role:
application
Description:

This symbol represents an n-ary function used to construct (or describe) vectors. Vectors in this CD are considered to be row vectors and must therefore be transposed to be considered as column vectors.

Example:
An example of vector using n arguments. The specific vector constructed in this example is [3,6,9].
$\left(3,6,9\right)$

## matrixrow

Role:
application
Description:

This symbol is an n-ary constructor used to represent rows of matrices. Its arguments should be members of a ring.

Example:
Representation of a row of a matrix of length two containing the integers [1,0]
$\left(\begin{array}{cc}1& 0\end{array}\right)$

 [Next: matrix] [Previous: vector] [Top]

## matrix

Role:
application
Description:

This symbol is an n-ary matrix constructor which requires matrixrow's as arguments. It is used to represent matrices.

Example:
Representation of a 2x2 identity matrix
$\left(\begin{array}{cc}1& 0\\ 0& 1\end{array}\right)$
