I notice that your variable is t01 while you are calling ode() with t0 instead of t01 as one of the arguments in your function myexample(). Besides, when you actually call myexample(), you mistakenly use a "." instead of a "," and that's why Scilab believes it is a field of some non existent structure and yields the error code.

But I find that this generates an error message. For example, in the first example obtained by typing help ode, the script fails to execute if the ode function is called inside a user-defined function. Is there any solution to this problem function ydot=f(t, y) ydot=y^2-y*sin(t)+cos(t) endfunction y0=0; t0=0; t=0:0.1:%pi; y = ode(y0, t0, t, f); plot(t,y) //This does not work if ode is called inside a user-defined function function [yy]=myexample(y0, t01, t) y = ode(y0, t0, t, f); plot(t,y) endfunction [yy] = myexample(y0.t0, t);//this call list the error "Attempt to reference field of non-structure array".
