【Abstract】 A fire control system is designated as an example to demonstrate the complexity of mathematical models of fire control systems, which can not theoretically infer the analytical formulation of first partial derivatives. Using numerical differentiation for solving first partial derivative of complex mathematical model is proposed. The numerical differential formulation,selecting differential steplength and determining results of numerical differentiation are introduced in detail. The calculating results are demonstrated by using Monte Carlo statistical method.更多还原
