Error while using dec2bin() : too many input arguments

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.

[Walter Roberson]

Please show

which -all dec2bin

in case you are getting a different dec2bin than is expected

i'm using MATLAB R2013a version

[ANJANA KRISHNAN A]

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?

[Walter Roberson]

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

[ANJANA KRISHNAN A]

output of which -all dec2bin is :

F:\MATLAB\RSA\dec2bin.m

C:\Program Files\MATLAB\R2013a\toolbox\matlab\strfun\dec2bin.m % Shadowed

Thank you sir!! I think i was getting the dec2bin of the folder RSA!!Now i renamed that script.it's ok,right??

You need to remove F:\MATLAB\RSA

from your MATLAB path. You can do that using pathtool

[ANJANA KRISHNAN A]

it works!

the output is a 35x1 char.
