Tools for numerical math calculations

Build Status Codacy Badge Codacy Badge

This repository contains tools for math numerical computation such as numerical integration and interpolation. The current implementation contains:

  • numerical integration using Gauss formula

    import numpy as np
    from numerical.integration import gauss
    
    def f(x):
        return np.power(x[0], 2)
    
    gauss.integrate(f, 0., 1.)  # 0.3333333
    
  • spline functions and theirs derivatives

    import numpy as np
    from numerical import splines
    import matplotlib.pyplot as plt
    
    x = np.arange(0, 4., 0.05)
    y = splines.schoenberg(x)
    yd1 = splines.schoenberg.deriv(x, order=1)  # first derivative
    yd2 = splines.schoenberg.deriv(x, order=2)  # second derivative
    # visualize results
    plt.plot(x, y)
    plt.plot(x, yd1)
    plt.plot(x, yd2)
    plt.show()

  • function interpolation

    import numpy as np
    from numerical import interpolate
    import matplotlib.pyplot as plt
    
    def fun(x):
        return 1 - np.power(x[0] - 0.5, 2)
    
    grid = np.array([np.arange(0, 1.0001, 0.25)])
    values = fun(grid)
    itp_fun = interpolate(values, grid)
    
    x = np.arange(0., 1.00001, 0.001).reshape(1, -1)
    y_intp = itp_fun(x)
    y_true = fun(x)
    
    plt.plot(x[0], y_intp)
    plt.plot(x[0], y_true)
    plt.show()
