Complex64

• 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 AND EXPORT

• 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.

• ImportString and ExportString support the Complex64 format.

ELEMENTS

• General Import elements:

	"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

• By default, Import and Export use the "Data" element.

• Import["file", {"Complex64", n}] reads the n single-precision complex number from file.

• Import returns Infinity for IEEE "infinity", and Indeterminate for IEEE "not-a-number".

• Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

OPTIONS

• General option:

ByteOrdering

-1

what byte ordering to use

• Import option:

"HeaderBytes"

0

how many bytes to skip at the beginning of the file
