Hi,
I am copying the code below from this page, but it says error
"Undefined function 'a' for input arguments of type 'char'."
Could anybody tell me what is wrong?
Thanks
a := [6, 9, 17, 0, 13, 9, 9, 12, 12, 12]:
b := [7, 8, 20, 2, 11, 8, 9, 12, 13, 15, 2, 14]:
q := plot::QQplot(a, b):
plot(q)

Provided you have the symbolic toolkit, at the MATLAB command line use
a = [6, 9, 17, 0, 13, 9, 9, 12, 12, 12];
b = [7, 8, 20, 2, 11, 8, 9, 12, 13, 15, 2, 14];
feval(symengine, 'plot::QQplot', a, b);

Check this:
I don't have r2012b version
a = [6, 9, 17, 0, 13, 9, 9, 12, 12, 12];
b = [7, 8, 20, 2, 11, 8, 9, 12, 13, 15, 2, 14];
plot::QQplot([a, b]);

Thanks,
On the :: it is giving the Error: Unexpected MATLAB operator.
Any suggestions?

Are you trying to enter this directly at the MATLAB command prompt?
You have to first enter
>>mupad
Then copy and paste the code in the MuPAD notebook and hit enter

Could you tell me the correct syntax for the command line?
It doesn't seem to like the ::
a = [6, 9, 17, 0, 13, 9, 9, 12, 12, 12];
b = [7, 8, 20, 2, 11, 8, 9, 12, 13, 15, 2, 14];
plot::QQplot([a, b]);

Do you have the Statistics Toolbox? If so you don't need to use MuPAD
a = [6, 9, 17, 0, 13, 9, 9, 12, 12, 12];
b = [7, 8, 20, 2, 11, 8, 9, 12, 13, 15, 2, 14];
qqplot(a,b)

Thanks, I thought the qqplot at this link was for continuous variables
And the qqplot at this link was for discrete variables (that is what the documentation says).
They do not produce the same plots?
I need to use the discrete option.
Thank you

And in MuPAD, all you have to do is paste what you have above into a code line.
