SIGNAL/RTS APPLICATION NOTES

10 Application Note 11

These formats are used by the following hardware platforms:

Little-endian

Big-endian

IBM PC Macintosh

VAX NexT

DEC Alpha Sun

IBM RS6000

SGi Iris

To transfer data into or out of MATLAB to a hardware platform using a different byte-order,

use the optional FORMAT parameter in the FOPEN statement to specify the byte-order order

of the incoming or outgoing data. MATLAB will then perform byte conversion as necessary.

For example, to import data from SIGNAL on the PC to MATLAB on a non-PC platform,

open the data file in MATLAB using the following (the field stands for IEEE format, little-

endian, the byte format of PC data). MATLAB will then convert the data from this format to

the format of its native machine.

fid = fopen ('myfile','rb','ieee-le')

Similarly, to export data from MATLAB on a non-PC platform to SIGNAL on a PC, have

MATLAB store the data in little-endian IEEE format (ready for use by SIGNAL on the PC)

by including the following:

fid = fopen ('myfile','wb','ieee-le')
