when i run this code:
M = 'Hello';
% Now encode:
Mbinlong = reshape(dec2bin(double(M),7).',[],1)
I get this error :
Error using dec2bin Too many input arguments.
why this happens? How can i resolve this error?

The code works as-is for me. Which MATLAB version are you using?

Please post the complete error message. I assume that another line is affected.

Please show
which -all dec2bin
in case you are getting a different dec2bin than is expected

when i use the same code without including the argument '7',the code actually works!
Mbinlong = reshape(dec2bin(double(M)).',[],1);
But it represents that text in binary using 65535 bits.why so? can i represent it with lesser number of bits?

Please show the output of
which -all dec2bin
R2013a did support passing the number of bits; see http://www.mathworks.com/help/releases/R2013a/matlab/ref/dec2bin.html
I think you are getting someone else's dec2bin

output of which -all dec2bin is :
F:\MATLAB\RSA\dec2bin.m
C:\Program Files\MATLAB\R2013a\toolbox\matlab\strfun\dec2bin.m % Shadowed

You need to remove F:\MATLAB\RSA
from your MATLAB path. You can do that using pathtool
