Why is there no piecewise tuple construction?

Question: Why doesn’t the same piecewise constructibility exist for arrays and tuples? My recollection is that piecewise construction was added to std::pair for one reason only: to support uses-allocator construction of the pair elements, i.e. to allow an allocator to be provided and conditionally passed to the elements if they support construction with an allocator … Read more

How to apply piecewise linear fit in Python?

You can use numpy.piecewise() to create the piecewise function and then use curve_fit(), Here is the code from scipy import optimize import matplotlib.pyplot as plt import numpy as np %matplotlib inline x = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ,11, 12, 13, 14, 15], dtype=float) y = np.array([5, 7, 9, 11, … Read more
