CHANGE LOG: [06-13-2018]

  • Copied/pasted Lucene's solution for preventing memory leak associated with memory mapped files. jmatio is now ok with Java 8 -> 11-ea This now requires Java 8.

[08-11-2016]

  • Cleaned javadocs

[09-10-2014]

  • Changing to maven nature
  • Adding query parsing

[2012-12-03]

  • Adding supprot for Java objects and Objects
  • Performance optimization

[05.10.2007]

  • Sparse matrix bugfixes by Jonas Pettersson (LU/EAB)
  • MatFileReader performance enhancements by Eugene Rudoy
  • new MatFileReader methods added

[02.03.2007]

  • Regression bug fixed: Double arrays created natively in Matlab are read incorrectly (reversed byte ordering)

[22.02.2007]

  • Added support:UInt8 array
  • MAJOR reading performance enhancement - reading is as fast as in Matlab now
  • Removed Log4j references

TODO:

  • Other array types (serialized objects (OPAQUE) is done partially)
  • Writer performance enhancement
  • Documentation and examples
  • Organize JUnit tests
  • Refactor exceptions
  • Make structures and cell arrays more user friendly

NOTE: Numerical arrays (MLDouble, MLUint8) are now backed by direct ByteBuffers. For really BIG arrays the maximum heap size for direct buffers may be modified by -XX:MaxDirectMemorySize=

[some.time.2006] Currently supproted data types are:

  • Double array
  • Char array
  • Structure
  • Cell array
  • Sparase array
