Help looping scalars in Euler Method function

I'd like to loop soln_Analytic (below) for different scalar values. As an example, it would run the function for h = .5, then for h = .6, to h = 3.0. The function below defines Euler's method where F is an anonymous function and t0, h, tfinal, and y0 are scalars.

 function yout = ode1_WorkingCode(F,t0,h,tfinal,y0) 
 y = y0; % put y0 into y
 yout = y; % put y into the output

 for t = t0 : h : tfinal - h 
 s = F(t,y);  y = y + h*s; 
 yout = [yout ; y];

Here I give the anonymous function, and define the scalar values. I think this is where I should put the for loop but I can't figure out how to execute it. Any help is appreciated.

 k = 0.2;
 F = @(t,y) -k*y
 t0 = 0;
 h = .5;
 tfinal = 5;
 y0 = 1;
 soln_Analytic = ode1_WorkingCode(F,t0,h,tfinal,y0)

hr - if you want your h to change from 0.5, 0.6,0.7,..., 3.0, then you can simply do

 for h=0.5:0.1:3.0
    % do your calculation
 end

Presumably you will want to save each result to an array (to avoid overwriting the value from the previous iteration).
