Error using TF (Transfer Function): Too many output arguments.

I am trying to run some code for Transfer Functions and keep getting an error. The code is for a class and was downloaded from the class page. Everyone else has no issues running the code, so it seems to be an issue strictly related to my installation of Matlab/My PC. I am running Matlab R2015a 32 bit. The only toolboxes installed are MATLAB 2015a, Simulink, Symbolic Math, and the Control Systems Engineering toolbox.

Code is as follows:

%%go over crating transfer functions and getting data from them:
%%another way:
s=tf('s') % let matlab know that s will be the laplace variable s
G=(s+1)/(2*s+3);

The output and error is as follows:

s =

    s

Continuous-time transfer function.

Error using  +  (line 63)
Too many output arguments.

Is that code part of a larger script, or are you only running those two lines?

[Michael Peterson]

Yes, it is tthe first couple lines of a much larger code. Regardless, the code does not allow any sort of mathematical operation (+,-,*,/) on the 's' tf variable.

‘Regardless, the code does not allow any sort of mathematical operation (+,-,*,/) on the 's' tf variable.’

True.

See the documentation on Model Interconnection (link) if you want to connect models in series, parallel, or other configurations.
