Constructor Detail

MatFileHeader

public MatFileHeader(java.lang.String description,
                     int version,
                     byte[] endianIndicator)

New MAT-file header

Parameters:

description - - descriptive text (no longer than 116 characters)

version - - by default is set to 0x0100

endianIndicator - - byte array size of 2 indicating byte-swapping requirement

Method Detail

getDescription

public java.lang.String getDescription()

Gets descriptive text

Returns:

getEndianIndicator

public byte[] getEndianIndicator()

Gets endian indicator. Bytes written as "MI" suggest that byte-swapping operation is required in order to interpret data correctly. If value is set to "IM" byte-swapping is not needed.

Returns:

- a byte array size of 2

getVersion

public int getVersion()

When creating a MAT-file, set version to 0x0100

Returns:

createHeader

public static MatFileHeader createHeader()

A factory. Creates new MatFileHeader instance with default header values:

• MAT-file is 5.0 version
• version is set to 0x0100
• no byte-swapping ("IM")

Returns:

- new MatFileHeader instance

toString

public java.lang.String toString()

Overrides:
