help me solve errors in this code

function out = dec2binvec(dec,n)
%DEC2BINVEC Convert decimal number to a binary vector.
%
%    DEC2BINVEC(D) returns the binary representation of D as a binary
%    vector.  The least significant bit is represented by the first 
%    column.  D must be a non-negative integer. 
% 
%    DEC2BINVEC(D,N) produces a binary representation with at least
%    N bits.
% 
%    Example:
%       dec2binvec(23) returns [1 1 1 0 1]
%
%    See also BINVEC2DEC, DEC2BIN.

% Error if dec is not defined.

if nargin < 1

     error('daq:dec2binvec:argcheck', 'D must be defined.  Type ''daqhelp dec2binvec'' for more information.');

end

% Error if D is not a double.

if ~isa(dec, 'double')

     error('daq:dec2binvec:argcheck', 'D must be a double.');

end

% Error if a negative number is passed in.

if (dec < 0)

     error('daq:dec2binvec:argcheck', 'D must be a positive integer.');

end

% Convert the decimal number to a binary string.

switch nargin

case 1
   out = dec2bin(dec);

case 2
   out = dec2bin(dec,n);
end

% Convert the binary string, '1011', to a binvec, [1 1 0 1]

out = logical(STR2NUM([fliplr(out);blanks(length(out))]')');

I get error in this code please help me.??? errors are mentioned below

Error using ==> vertcat
CAT arguments dimensions are not consistent.

Error in ==> dec2binvec at 45
out = logical(STR2NUM([fliplr(out);blanks(length(out))]')');

You are calling the routine incorrectly. You are calling it with a vector or array rather than a scalar. dec2binvec() accepts only a scalar input. Your code for ReadBinFile is incorrect in calling

bits_tmp = dec2binvec(outBytes')';

It is not clear what it is expecting, but I suspect that it could be written as

bits_tmp = dec2bin(outBytes')' - '0';
