6 Data Import and Export
Sharing Memory Between Applications. Memory-mapped files also
provide a mechanism for sharing data between applications, as shown in the
figure below. This is achieved by having each application map sections of
thesamefile. Thisfeaturecanbeusedto transfer large data sets between
MATLAB and other applications.
Also, within a single application, you can map the same segment of a file
more than once.
Limitations of Memory-Mapping in MATLAB
MATLAB restricts the size of a memory map to 2 gigabytes, and on some
platforms, requires that you set up your memory-mapping so that all data
access is aligned properly. See the following section, “Maximum Size of a
Memory Map”, for more information.
