Hello everyone. I have a long-standing problem, how to calculate the similarity between the two curves that have been fitted. Thank you for your enthusiastic answers.

What is your definition of "similarity"? Is x1 more similar to x2 or x3? Why?
x1 = 1:5
x2 = x1 + 1
x3 = [1:4 7]
How about x4?
x4 = x1 + (-0.5:0.25:0.5)
What's most simlar to the black line in the plot below? The cyan with upward pointing triangles, the green with downward pointing triangles, or the magenta with rightward pointing triangles?
plot(x1, x1, 'k-+', x1, x2, 'c-^', x1, x3, 'g-v', x1, x4, 'm->')
