%  Description: This file contains a long list of examples demonstrating the abilities of
%               the translator. Most of these examples come straight from the MathML spec. They
%               were used during the development of the interface and should all be correctly
%               translated into OpenMath.

%  Description: This file contains a long list of examples demonstrating the abilities of
%               the translator. Most of these examples come straight from the CDs. They
%		were used during the development of the interface and should all be correctly
%		translated into MathML.

% The following two examples show how the translator
% can deal with matrices represented either in columns
% or rows. The translator then converts matrices
% represented in columns into ones represented in
% rows. Mapping to MathML is then possible.

% The integral symbols defint and int are ambigious as defined
% in the CDs. They do not specify their variable of integration
% explicitly. The following shows that when the function
% to integrate is defined as a lambda expression, then the
% bound variable is easily determined. However, in other
% cases, it is not possible to determine the bound variable.
