so i got a function which i did as home work a few days ago tested it ,it ran ,now it doesn't want to run anymore i don't know how to fix it ,because i want to do a few more examples of ode45 and i get same error . The files have not been opened/modified since i wrote/tested them .

the function (which is saved correctly)

function dy=ec1L10(x,y)

dy=4*exp(0.8*x)-0.5*y

and the script

[x y]=ode45('ec1L10',0:0.25:4,2);

plot(x,y);grid on ; axis tight;
