.mat
files in a memory efficient manner. Many implementations are
based on the JMatIO library (see com.jmatio.*
packages).
To write matlab files or output, an {@link ch.javasoft.jsmat.MatFileWriter MatFileWriter}
or {@link ch.javasoft.jsmat.MatOutputStreamWriter MatOutputStreamWriter} is
used. Both classes support writing
{@link ch.javasoft.jsmat.variable.MatAllocated MatAllocated} and
{@link ch.javasoft.jsmat.variable.MatReserved MatReserved} variables.
MatAllocated
variables contain data which is already allocated in
memory. It is the most convenient way to write data to the .mat
file. However, for very large data structures, such as matrices with millions of
rows or columns, it might be more appropriate to write the values to the file in
a stream-like manner. When a reserved variable is constructed, only the
size must be known. The data is then appended step by step — depending on
the underlying function generating the data.
