Just trying to plot a piecewise defined function in python but having trouble with an error. "The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()". I understand that the issue is python cannot analyze the truth of an entire array at once, however I don't believe a.any() or a.all() resolves the problem. Here are my two attempts at the code: x = linspace(0,3,1000) def S(x): if 0 <= x <= 1: return -1 + x - (5/9)*x**2 + (5/9)*x**3 elif 1 <= x <= 2: return (14/9)*(x-1) + (10/9)*(x-1)**2 - (2/3)*(x-1)**3 elif 2 <= x <=3: return 2 + (16/9)*(x-2) - (8/9)*(x-2)**2 - (1/9)*(x-2)**3 plot(x, S(x), 'k') show() x = linspace(0,3,1000) plot(x, piecewise(x, [x<=1, 1<=x<=2, x>=2], [lambda x: -1 + x - (5/9)*x**2 + (5/9)*x**3, lambda x: (14/9)*(x-1) + (10/9)*(x-1)**2 - (2/3)*(x-1)**3, lambda x: 2 + (16/9)*(x-2) - (8/9)*(x-2)**2 - (1/9)*(x-2)**3])) Continue reading...
