Here’s the solution:
# Exercise 5: Load Radioactive Decay Data # Load Data filename = "Data/Polonium.txt" [t,N,dN] = loadtxt(filename, unpack=True) xlabel("time [days]") ylabel("$N$") # Plot Data errorbar(t, N, fmt='o', label='Data', yerr=dN)
So what’s going on ?
We’ve already seen every single one of these commands in the previous exercises; if something seems unfamiliar, go back and check. Make sure you understand what each line does.
