| Abstract: | In this paper, an algorithm named the method of cyclic search is suggested to make full use of observed values to determine the initial values of parameters during double exponential curve is fitted in the meaning of least square by means of Gauss Newton method. According to this algorithm, a Qbasic procedure can be progremed to fit automatically the designated one type of 20 single or double exponential function curves. And it is successful to test and verify this algorithm in several examples. |
