WebLagrange Polynomial Interpolation¶. Rather than finding cubic polynomials between subsequent pairs of data points, Lagrange polynomial interpolation finds a single polynomial that goes through all the data points. This polynomial is referred to as a Lagrange polynomial, \(L(x)\), and as an interpolation function, it should have the property \(L(x_i) = … Web10 Mar 2024 · Note that runge-kutta object calls x as "t" and z as "y".:param z_at_0: the value of the vector z=[y, y'] at the left boundary point. should be list or array.:param integrator: the runge-kutta numerical integrator object:param areafunction: a function that takes x and gives back a 2-vec [A(x), dA(x)/dx]:param length: the length of the domain to ...
