- The DTD support for XML charting is now located at http://www.roguewave.com/products/jmsl/chart.dtd.
- Some JMSL classes require user defined methods. It is the responsibility of the user to assure that these methods do not return NaN, infinity or negative infinity values.
- The QuickStart Guide is no longer offered.
- Use of JMSL requires a Java development environment, such as Oracle's JDK 7.0.
- Class
`SparseLP`

can accept inputs in Compressed Sparse Column (CSC), or Harwell-Boeing format. See Users' Guide for the Harwell-Boeing Sparse Matrix Collection. - Variable length argument lists (varargs) do not display correctly in the documentation. A note has been added where this occurs and the issue will be corrected in the future.
- In addition to the jar file,
`jmsl.jar`

, users have the option of using jar files containing subsets of the entire product. The jar file,`jmslnumerics.jar`

, does not contain any references to javax.swing or JMSL charting classes. The jar file,`jmslchart.jar`

, contains the JMSL charting classes. It does not contain any of the numeric classes. - For Windows-based systems, the user
may experience different results between OpenGL and Direct 3D
(D3D) when printing JMSL 3D graphs. These differences may be
related to differences in video hardware and drivers, as well as
versioning issues of OpenGL and D3D. The user should experiment
with each method to determine the optimal method for printing 3D
graphs. The default is to use OpenGL. To use D3D set the Java
system property
`j3d.rend`

to`d3d`

. This can be done on the command line using the option`-Dj3d.rend=d3d`

. The current serialization support is appropriate for short term storage or RMI between applications running the same version of JMSL.*Serialization of JMSL classes will not be compatible with future JMSL releases.*
