Version 5 mat-file format The 8-byte data element tag is composed of two, 32-bit fields Data Typ Number of Byte Data Type. The Data Type field specifies how the data in the element should be interpreted, that is, its size and format. The MAT-file format supports many data types including signed and unsigned, 8-bit, 16-bit, 32-bit, and 64-bit data types and a special data type that represents MATLAB arrays. Table 1 lists al these data types with the values used to specify them. The table also includes symbols that are used to represent these data types in the examples in this document Table 1: MAT-File Data Types AAT-File Data Type Value Symbol 8 bi t, si gned miNts 16-bit, si gned 1234 mi UI NT8 miINT16 16-bit, unsi gned mi UINT16 32-bit, si gned 32-bit, unsi gned mi NT32 I EEE 754 single format 7 I EEE 754 double format 9 mi dOuble Reserved 10 Reserved 64-bi t, si gned 12 mi INT64Version 5 MAT-File Format 7 Tag The 8-byte data element tag is composed of two, 32-bit fields: • Data Type • Number of Bytes Data Type.
