RAWREAD Read N-dimensional Array From File

Section: Input/Ouput Functions

Usage

The syntax for rawread is

   function x = rawread(fname,size,precision,byteorder)

where fname is the name of the file to read from, and size is an n-dimensional vector that stores the size of the array in each dimension. The argument precision is the type of the data to read in:

  • 'uint8','uchar','unsigned char' for unsigned, 8-bit integers
  • 'int8','char','integer*1' for signed, 8-bit integers
  • 'uint16','unsigned short' for unsigned, 16-bit integers
  • 'int16','short','integer*2' for signed, 16-bit integers
  • 'uint32','unsigned int' for unsigned, 32-bit integers
  • 'int32','int','integer*4' for signed, 32-bit integers
  • 'uint64','unsigned int' for unsigned, 64-bit integers
  • 'int64','int','integer*8' for signed, 64-bit integers
  • 'single','float32','float','real*4' for 32-bit floating point
  • 'double','float64','real*8' for 64-bit floating point
  • 'complex','complex*8' for 64-bit complex floating point (32 bits for the real and imaginary part).
  • 'dcomplex','complex*16' for 128-bit complex floating point (64 bits for the real and imaginary part).

As a special feature, one of the size elements can be 'inf', in which case, the largest possible array is read in. If byteorder is left unspecified, the file is assumed to be of the same byte-order as the machine FreeMat is running on. If you wish to force a particular byte order, specify the byteorder argument as

  • 'le','ieee-le','little-endian','littleEndian','little'
  • 'be','ieee-be','big-endian','bigEndian','big'
