1 function y = forward_euler1(x0, y0, f, h)
2 ## Compute one iteration of the forward Euler method.
6 ## * ``x0`` - The initial x-coordinate.
8 ## * ``y0`` - The initial value y(x0).
10 ## * ``f`` - The function y' = f(x,y) of two variables.
12 ## * ``h`` - The step size.
16 ## The approximate value of y(x) at x = x0+h.
