Polyfit
Least square polynomial curve fitting
Syntax
polyfit(x, y, m) |
x,y are vectors of the same size, m is an positive integer and m>=2 |
The input vectors x, y contains the data points for the curve fitting. Each data point is given by (x[i], y(i)). polyfit(x,y,m) return a vector whose elements are the coefficients of the polynomial fitting function. m is the order of the polynomial fitting function. |
Example
Input |
Output |
x = linspace(0, 2*PI/30.0) y = sin(x) polyfit(x,y,8) |
