when we try to run the example given in Matlb help it is not getting executed. The code is
t = -10:10;
x = t.^3 + 6*t.^2 + 4*t + 3;
bp = 0;
y = detrend(x,1,bp,'SamplePoints',t,'Continuous',false);
plot(t,x,t,y,t,x-y,':k')
The error coming is
Error using detrend
Too many input arguments.
Please help in coming out of the issue...

Some of the functionality you're trying to use was introduced in release R2019a. You're likely using an older release. Check if the options 'SamplePoints' and 'Continuous' are listed in the documentation for detrend included in your installation since the online documentation is for the most recent release.
