function msg = genMsg
%#codegen
persistent msgBinRows msgBinCols msgBin;
coder.extrinsic('imread');
% count;
if isempty(msgBin)
%count = 0;
imgmatRows = 256;
imgmatCols = 256;
imgmat = zeros(imgmatRows,imgmatCols);
imgmat = imread('cameraman.tif');
imgvec = reshape(imgmat, 1, imgmatRows * imgmatCols);
msgBin = de2bi(imgvec, 'left-msb');
[msgBinRows, msgBinCols] = size(msgBin);
end
msg = reshape(double(msgBin).', msgBinRows*msgBinCols, 1);
When I run this code it produces the following error
Data 'msg' (#24) is inferred as a variable size matrix, while its specified type is something else
How can I fix this problem?

At the beginning, initialize
msg = zeros(256*256*8, 1);
Warning your de2bi() call really should specify "n".
