Does student version include SR_Control_Toolbox?
显示 更早的评论
I am receiving the error below when trying to use the tf function. I purchased the Student Edition and I was under the impression that my license would include those basic matlab functions.
Below is the error message I'm receiving.
Error using tf
License checkout failed.
License Manager Error -5

We are probably going to need to see what you passed to the function, including its class() . You do seem to have Control Systems Toolbox and you seem to have it licensed, but possibly you asked tf() to work on data that is of a different class, perhaps even something restored from a very old .mat file.

Yes, that really looks there is something on the path that confuses here. I doubt a clean slate installation has this.

Your R2015b Student Version may or may not have the Control System Toobox (which is a prerequisite for "tf" transfer functions. It really depends on what you have purchased. Can you provide the output of the "ver" command? It returns all installed toolboxes.
What puzzles me is the "SR_Control_Toolbox" name. To my best knowledge, this links to a product that is pretty old and not available for R2015b. Can you also share the return result for the command
which tf -all

When I looked, the only reference to SR_Control_Toolbox seemed to be the Optimal Control Toolbox in about 2004.
The regular Student Version license does include Control System Toolbox, but it is also possible for institutions to request customized Student Version packages for distribution to students; those could have just about any combination of the toolboxes available to students.

Yeah, I was fuzzy with "pretty old" :-D
Side note: Today, one could purchase a MATLAB only SV.

Hi, I have similar issue. When I run which tf -all
C:\Program Files\MATLAB\R2015b\toolbox\control\control\@tf\tf.m % tf constructor C:\Program Files\MATLAB\R2015b\toolbox\control\control\@DynamicSystem\tf.m % DynamicSystem method, Has no license available C:\Program Files\MATLAB\R2015b\toolbox\dsp\filterdesign\@mfilt\tf.m % mfilt method, Has no license available C:\Program Files\MATLAB\R2015b\toolbox\dsp\filterdesign\@adaptfilt\tf.m % adaptfilt method, Has no license available C:\Program Files\MATLAB\R2015b\toolbox\shared\controllib\engine\@StaticModel\tf.m % StaticModel method C:\Program Files\MATLAB\R2015b\toolbox\signal\signal\@dfilt\tf.m % dfilt method, Has no license available
This the output I got.
Can you help with this issue I am also using MATHLAB R2015b
Thanks, Nisarga
