In quantum optics, it is often necessary to simulate the equations of motion of a system coupled to a reservoir. Using a Schrö dinger picture approach, this can be done either by integrating the master equation for the density matrix[1] or by using some state-vector based approach such as the quantum Monte Carlo technique

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).
