function y = forward_euler1(x0, y0, f, h) ## Compute one iteration of the forward Euler method. ## ## INPUT: ## ## * ``x0`` - The initial x-coordinate. ## ## * ``y0`` - The initial value y(x0). ## ## * ``f`` - The function y' = f(x,y) of two variables. ## ## * ``h`` - The step size. ## ## OUTPUT: ## ## The approximate value of y(x) at x = x0+h. ## y_prime = f(x0,y0); y = y0 + h * y_prime; end
