% write_int16_hex(name,A)

% Write elements of matrix A in .dat format, suitable for loading
% into Code Composer Studio.

% Elements are rounded to to 16-bit signed integer format
% and the values are stored in hex-format (little endian)

A=A(:).';

if mod(N,2)
    A(end+1)=0; % hex format stores 32 bit words, zero-pad to even length

% convert to double and/or round to nearest integer
A=double(int16(A));
