Easy CurveFit

Description

Easy CurveFit is a very easy tool to fit curve. Only three steps you should do, and youll get the fitting curve and the needed parameters. The models include linear and nonlinear.Regressions:
1. Linear Fit, y=a+bx;
2. Quadratic Fit, y=a+bx+cx^2;
3. Compound Fit, y=ab^x;
4. Logatithmic Fit, y=a+b*ln(x);
5. Exponential Fit, y=a*exp(bx);
6. Power Fit, y=a*x^b;
7. Inverse Fit, y=a+b/x;
8. hyperbola Fit, y=ax/(b+x);
9. Geometric Fit, y=ax^(bx);
10. Geometric Fit, y=ax^(b/x);How to use:
Step1:
Open the data file *.dat or *.txt, the points will be plot in the figure;
such as gaosi.dat:
* 10 160 * 16 151 * 20 114 * 25 128 * 31 85 * 36 91 * 40 75 * 45 76 * 51 66 * 56 60 * 60 61 * 65 60
