I'll give your suggestion a try. My suggestion: try to read the first variable first. The types of variables featuring 2 bytes are not a lot. Or simply call fread once, and then swap the byte values of the first variable. Off-Canvas Navigation Menu Toggle. Main Content. BinaryFileReader Read data from binary file expand all in page. Description The dsp. To read data from a binary file: Create the dsp. BinaryFileReader object and set its properties. Call the object with arguments, as if it were a function.

BinaryFileReader fname. BinaryFileReader fname,Name,Value. BinaryFileReader 'myFilename. Properties expand all Unless otherwise indicated, properties are nontunable , which means you cannot change their values after calling the object.

Filename — Name of file 'Untitled. HeaderStructure — Size of header struct 'Field1',[] default structure. SamplesPerFrame — Number of samples per output frame default positive integer.

NumChannels — Number of channels 1 default positive integer. DataType — Type of data in file 'double' default 'single' 'int8' 'int16' 'int32' 'int64' 'uint8' 'uint16' 'uint32' 'uint64'. IsDataComplex — Specify data complexity false default true. Output Arguments expand all data — Data output vector matrix.

Object Functions To use an object function, specify the System object as the first input argument. For example, to release system resources of a System object named obj , use this syntax: release obj.

Common to All System Objects. Examples collapse all Write and Read Binary Files. Open Script. Write the Data Specify the file header as a structure with the following fields: DataType set to double.

Complexity set to false. FrameSize number of rows in the data matrix set to NumChannels number of columns in the data matrix set to 1. Complexity; reader. DataType; reader.

NumChannels; reader. Write and Read Matrix Data. Open Live Script. Write the Data Write the matrix A to the binary file Matdata. The header has the following format: DataType set to double. FrameSize number of rows in the data matrix set to 3. NumChannels number of columns in the data matrix set to 4. BinaryFileWriter 'Matdata. BinaryFileReader 'Matdata.

Read Header Data. BinaryFileReader 'myfile. A datatype: double. B datatype: single. Read Complex Data. Write and Read Fixed-Point Data.

Write the Fixed-Point Data Create an fi object to represent signed random numbers with a word length of 14 and a fraction length of BinaryFileWriter 'myFile. BinaryFileReader 'Filename' , 'myFile.
