Running into error using "inline" and "euler"

Im trying to run this code:

f=inline('2*y','t''y');
t=linspace(0,.5,100); y=3*exp(2*t);
[t50,y50]=euler(f,[0,.5],3, 50);

I get the error "Undefined function 'euler' for input arguments of type 'inline'."

Any idea how to fix this?

https://www.mathworks.com/help/symbolic/euler.html

"euler(n) returns the nth Euler number.

euler(n,x) returns the nth Euler polynomial."

That is the only euler() function provided by Mathworks, and it does not accept four arguments.
