Identification of non-linear functions:polynomial+exponential

44 Views Asked by At

Is there a way to perform a non linear least square to identify the following function:

$$\alpha_2\cdot x^2 + \alpha_1\cdot x + \alpha_0 + \beta e^{\frac{\gamma}{x}}=Y$$

I aim at identifying the parameters $\alpha_i, \beta $ and $\gamma$ without iteration.The exponential term is making it difficult to use the Least Squares, and I wonder if there is any other technique or to re-write the equation
