MatLAB script конвертация float из десятичной системы счисления в hex для Code Composer Studio

% Create scrip that convert float numbers to hexidecimal.
% This file is useful for example if we need to load *.dat file to Code
% Composer Studio. But this dat-file can understand only hexidecimal format
% of number types such as int, long, float.
 
% For start to work You must to set the input/output file name and path 
%and data type working with
filename = 'dspInputSamples.dat';
outFileName = 'dspInputSamplesHEX.dat';
dataType = 'single';   %data of this type we read from input file with 
                       % "filename" name
 
%descriptor of the file that must be opened
%fid = fopen('my_file.dat', 'wb');     % открытие файла на запись
inputFID = fopen( filename, 'rb');
if inputFID == -1
    error('input File is not opened');
end
 
%descriptor of teh output file
outputFID = fopen(outFileName, 'wt');
if outputFID == -1
    error('output File is not opend');
end
 
%initialize the 1-D row vector. In this value we will save unput data
rowVec = 0;
 
%READ FROM FILE
%samplesCnt - the number of elements read
[rowVec, samplesCnt ] = fscanf( inputFID, '%f', inf ); 
 
%preallocate 1D column vector
rowVecHEX = zeros( 1, samplesCnt, dataType);
 
%CONVERTION
rowVecHEX = num2hex( single( rowVec ) );
 
%WRITE TO FILE
A = rowVecHEX';
for k = 1:samplesCnt
    lastSignificant_16_bits =  A(5:8, k);
    mostSignificant_16_bits = A(1:4, k);
    fprintf( outputFID, '0x%c%c%c%cn', lastSignificant_16_bits );
    fprintf( outputFID, '0x%c%c%c%cn', mostSignificant_16_bits );
end
 
 
%display the row vector
disp( rowVecHEX );
 
fclose( inputFID );
fclose( outputFID );
