SYNOPSIS ^

function J= filter_jacobian( fwd_model, img)

DESCRIPTION ^

 FILTER_JACOBIAN: J= filter_jacobian( fwd_model, img)

 Filter a jacobian matrix by a specified filter function
 INPUT:
  fwd_model = forward model
  fwd_model.filter_jacobian.jacobian = actual jacobian function (J0)
  fwd_model.filter_jacobian.filter   = Filter Matrix (F)
  img = image background for jacobian calc
 OUTPUT:
  J         = Jacobian matrix = F*J0
