I'm trying to run the following code in Matlab and I can't get around it:

%---------------------------------------------------------------------------------------------------------------------------------

%Define modified euler function function euler(func, y0, delt,tf) %Compute t value t = 0:delt:tf; %Assign value y(1)=y0; %Loop for i = 1:length(t)-1 %Compute y value y(i+1) = y(i) + delt * feval(func,t(i) + delt/2, y(i) + delt*feval(func,t(i),y(i))); %Compute t t(i+1) = y0 + delt*i; end %Plot value plot(t,y) %Label xlabel('time') %Label ylabel('y') %Display disp(y(end)) end

%Define function function z = eqn(t) z = 14*t - 3; end %Plot fplot('',[0 10], 'r:') %Call method euler(@eqn,5,0.1,10)

%----------------------------------------------------------------------------------------------------------------------

Then I receive the following error:

>> euler Error: File: euler.m Line: 29 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "eqn".)

Any help fixing the code to run would be helpful.
