how can i convert the data in attached mat file into binary format with 32 bit width?

I want to convert the mat file data into binay/hex format & save it in a text file.

The data in mat file is in double format.

p.s: Please help me its urgent or forward this question to someone who can answer.

If you requied anything else please inform.

Hi Vinay,

To convert “rf_data” from a “.mat” file into binary and hexadecimal formats in MATLAB, load the file to access the “rf_data” variable, ensuring it is in double format.

Open text files for binary and hexadecimal outputs. For each element in “rf_data”, typecast it to “uint64” and convert it to a 64-bit binary string using “dec2bin” and a 16-character hexadecimal string using “dec2hex”.

Write these strings to the respective files and close the files after processing. This efficiently stores the data in both formats.

Below is the MATLAB code to achieve the same:

matFile = 'data.mat'; 

% Load the data
dataStruct = load(matFile);
rf_data = dataStruct.rf_data;

% Check if the data is in double format and correct dimensions
if ~isa(rf_data, 'double') || size(rf_data, 2) ~= 1
    error('The rf_data is not a double array.');
end

% Open text files to write the binary and hex data
binaryFile = 'rf_data_binary.txt'; % File for binary data
hexFile = 'rf_data_hex.txt';       % File for hex data

% Open files for writing
binFID = fopen(binaryFile, 'w');
hexFID = fopen(hexFile, 'w');

% Convert each element to binary and hex, and write to files
for i = 1:numel(rf_data)
    % Convert to binary
    binaryStr = dec2bin(typecast(rf_data(i), 'uint64'), 64);
    fprintf(binFID, '%s\n', binaryStr);
    
    % Convert to hex
    hexStr = dec2hex(typecast(rf_data(i), 'uint64'), 16);
    fprintf(hexFID, '%s\n', hexStr);
end

% Close the files
fclose(binFID);
fclose(hexFID);

Please find attached the documentation of functions used for reference:

I hope this will help in resolving the issue.
