MAT-File Format - SERC

1 MAT-File FormatDimensions Array SubelementThis subelements Specifies the size of each dimension of the array. Thissubelement is common to all array types. For more information, see“Dimensions Array Subelement” on page 1-17.Array Name SubelementThis subelement specifies the name assigned to the structure. This subelementis common to all array types. For more information, see “Array NameSubelement” on page 1-18.Field Name Length SubelementThis subelement specifies the maximum length of a Field Name. MATLAB setsthis limit to 32 (31 characters and a NULL terminator). In a MAT-file created byMATLAB, this subelement always uses the compressed data element format.Field Names SubelementThis subelement specifies the name of each field in the structure as a series of8-bit (miINT8) character arrays. The value of the Field Name Lengthsubelement determines the length of each field name array (32 bytes). Fieldnames must be NULL-terminated.Fields SubelementThis subelement contains the value stored in a field. These values areMATLAB arrays, represented using the miMATRIX format specific to the arraytype: numeric array, sparse array, cell, object or other structure. See theappropriate section of this document for details about the MAT-file format ofeach of these array type. MATLAB reads and writes these fields incolumn-major order.1-30
