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.
