Mathematica Import/Export Format

Complex64

Uniform sequence of IEEE single-precision complex numbers.
Binary data format.
  • Import can read any binary data as a sequence of 64-bit complex numbers.
  • Export converts a list of integer, real, or complex numbers to a sequence of binary 64-bit complex numbers.
  • IEEE double-precision numbers can be imported and exported using the "Complex128" format.
  • Import["file", "Complex64"] imports any file as IEEE single-precision complex numbers, returning a packed array of real numbers.
  • Export["file", list, "Complex64"] exports a list of complex numbers to file.
  • Import["file", {"Complex64", elem}] or Import["file", elem ] imports the specified element from file.
  • Import["file", {"Complex64", {elem1, elem2, ...}}] imports multiple elements.
  • See the reference pages for full general information on Import and Export.
"Elements" elements and options available in this file
"Rules"full rules for each element and option
"Options"rules for options, properties, and settings
  • Data representation element:
"Data"list of complex numbers
  • Import["file", {"Complex64", n}] reads the n^(th) single-precision complex number from file.
  • Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.
  • General option:
ByteOrdering-1what byte ordering to use
"HeaderBytes"0how many bytes to skip at the beginning of the file
