  • Ordinary Differential Equations — GSL 2.6

    A modified Newton iteration method is used to solve the system of non-linear equations. Method order varies dynamically between 1 and 5. The method is generally suitable for stiff problems. This stepper requires the Jacobian and the access to the driver object via gsl_odeiv2_step_set_driver ().

  • Linear Least-Squares Fitting — GSL 2.6 documentation

    One way of dealing with ill-conditioned matrices is to use a “truncated SVD” in which small singular values, below some given tolerance, are discarded from the solution. The truncated SVD method is available using the functions gsl_multifit_linear_tsvd() and gsl_multifit_wlinear_tsvd(). Another way to help solve ill-posed problems is to include a regularization term in the least squares minimization

  • The Ziggurat Method for Generating Gaussian

    The Brent-Dekker method (referred to here as Brent’s method) combines an interpolation strategy with the bisection algorithm. This produces a fast algorithm which is still robust. On each iteration Brent’s method approximates the function using an interpolating curve. On the first iteration this is a linear interpolation of the two endpoints.

  • One Dimensional Root-Finding — GSL 2.6

    If the interpolating point is not accepted then the algorithm falls back to an ordinary golden section step. The full details of Brent’s method include some additional checks to improve convergence. gsl_min_fminimizer_quad_golden¶ This is a variant of Brent’s algorithm which uses the safeguarded step-length algorithm of Gill and Murray.

  • One Dimensional Minimization — GSL 2.6

    2019-6-13 · We now need to find a formula for the area of the ring. Because we are using rings that are centered on a vertical axis (i.e. parallel to the (y)-axis) we know that the area formula will need to be in terms of (y).Therefore, the equations of the curves will need to be in terms of (y) and so we’ll need to rewrite the equation of the line to be in terms of (y).

By variance, we are referring to the width of the bell shape curve.
