simple traduction from ode45 to ode15i

Hello all,

could you explain to me how to solve a differential system with matlab please?

with ode45 I know:

main.m

A=eye(3)+5;
B=1:1:3;     B=B';
[t,y]=ode45(@(t,y)equadiffOde45(t,y,A,B), [0 100], zeros(1,length(B)));

myFun.m

function dy=myFun(t,y,A,B)
dy=zeros(length(B),1);
dy(:,1)=A*y+B;

but I can not find the equivalent with ode15i

could you please show me the equivalent code but with ode15i ?

there are two things I do not understand: 1) the form in which must be written myfun 2) the call ode15i more particularly the initial derivative (it should be 0 not always?)

thank you for your help
