JMatIO is a JAVA library to read/write/manipulate with Matlab binary MAT-files.

For really BIG arrays the maximum heap size for direct buffers may be modified by -XX:MaxDirectMemorySize=<size> [some.time.2006] Currently supproted data types are: + Double array + Char array + Structure + Cell array + Sparase array
