Hi!
I've started getting errors when attempting to call some new class functions which I've written.
num1=[10]; den1=[1,5,100];
num2=[1,12]; den2=[8,25];
[num,den]=series(num1,den1,num2,den2);
The error message I get is the following:
Check for missing argument or incorrect argument data type in call to function 'series'.

On your system, the Control System Toolbox is not installed, or license cannot be found, or for some reason it is not present on the path.
I think you are ending up invoking the series() function from the Symbolic Toolbox.
What shows up for
which -all series

Thanks for the answer, exactly the license cannot be because is an academic, I tried with
which -all series
and get this:
C:\Program Files\MATLAB\R2019a\toolbox\symbolic\symbolic\@sym\series.m % sym method
Please help me to solve this problem.
