      GSL2 use new Jacobian function gsl_multifit_fdfsolver_jac · e6fad7a9
      Liam M. Healy authored
      Function #'jacobian calls GSL2 function gsl_multifit_fdfsolver_jac
      with a second optional argument, this argument is the matrix into
      which the jacobian is written. If it is NIL, than the matrix is
      created with the new function #'make-jacobian-matrix. Covariance
      calculation #'ls-covariance calls #'jacoabian as in GSL1, but needs to
      pass result to #'mpointer to get a C pointer. To avoid reallocating
      covariance matrix repeatedly, call #'make-jacobian-matrix outside the
      iteration loop and pass as argument to ls-covariance, as shown in
      example #'nonlinear-least-squares-example.
