Methods

__call__(x, y[, mth]) Evaluate spline at positions x,y.
ev(xi, yi) Evaluate spline at points (x[i], y[i]), i=0,...,len(x)-1
get_coeffs() Return spline coefficients.
get_knots() Return a tuple (tx,ty) where tx,ty contain knots positions of the spline with respect to x-, y-variable, respectively.
get_residual() Return weighted sum of squared residuals of the spline
integral(xa, xb, ya, yb) Evaluate the integral of the spline over area [xa,xb] x [ya,yb].
