MATLAB® DataPlugin

This DataPlugin supports the reading/importing and writing/exporting of data files created by The MathWorks, Inc. MATLAB® Software.

MAT files are written by MATLAB® from The Mathworks. This DataPlugin allows to import and export MATLAB® files and directly read *.MAT files.

Supported Features:

• IMPORT
  • Files with homogeneous variable types of less than 3D dimensionality.
  • Homogeneous variables of data type CHAR, LOGICAL, INT8, UINT8, DOUBLE, SINGLE, INT16, UINT16, INT32, UINT32, INT64, and UINT64.
  • Loading all allowable variables from a given *.MAT file and ignoring any non-allowable variables during import.
  • Reading text channels from the MATLAB® file.
  • STRUCT data, where each field is a variable.
  • CELL data from *.DAT files.
  • COMPRESSED data from *.MAT files.
  • BigEndian data type.
  • LittleEndian data type.
• EXPORT
  • The DataPlugin displays channels in the Data Portal as *.MAT files by sending those channels to variables in the same way as they were originally imported.
  • Writing text channels to strings from the MATLAB® file.
  • The DataPlugin no longer decorates variable names with a 'v_' prefix. 
  • The DataPlugin no longer writes a log file.
  • A separate time channel is created for waveform channels.

 

Non-Supported Features:

• Loading variables in a *.MAT file of heterogeneous data types such as OBJECT and FUNCTION.
• Variables with an invalid class type are ignored.
• Three-dimensional arrays

 

File Extension:	*.MAT
Direction:	Read / Write
Last Change:	June 14, 2013 [1.2.0.5279]
Update Information:	The following changes have been made to this version: Fixed memory issue for large data files. The DataPlugin ignores variables which have an invalid class type.
