Module scid.ports.minpack.fdjac1


fdjac1(fcn, n, x, fvec, fjac, ldfjac, iflag, ml, epsfcn, mu, wa1, wa2)This subroutine computes a forward-difference approximation to the n by n Jacobian matrix associated with a specified problem of n functions in n variables. If the Jacobian has a banded form, then function evaluations are saved by only approximating the nonzero terms.
