Curve fitting problems occur in many scientific areas. The typical case is that you wish to fit the relation between some response y and a one-dimensional predictor x, by adjusting a (possibly multididoi:10.1007/978-0-387-79054-1_16Peter Dalgaard...
lsqcurvefit enables you to fit parameterized nonlinear functions to data easily. You can also use lsqnonlin; lsqcurvefit is simply a convenient way to call lsqnonlin for curve fitting. In this example, the vector xdata represents 100 data points, and the vector ydata represents the associated ...

The basic concept of the Arps' hyperbolic decline curve analysis is nonlinear curve fitting. However, the difficulty of finding a proper nonlinear algorithm to tune the Arps' hyperbolic decline equation to match historical oil production has forced analysts to use the exponential and harmonic declines...
