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 #'makejacobianmatrix. Covariance calculation #'lscovariance calls #'jacoabian as in GSL1, but needs to pass result to #'mpointer to get a C pointer. To avoid reallocating covariance matrix repeatedly, call #'makejacobianmatrix outside the iteration loop and pass as argument to lscovariance, as shown in example #'nonlinearleastsquaresexample.
