MiniMaxApproximation[expr, {x, {x_0, x_1}, m, n}] finds the rational polynomial function of x, with numerator order m and denominator order n, that gives a mini-max ...
As of Version 6.0, NIntegrate natively supports InterpolatingFunction objects.
OrderStarInterpolation is an option to OrderStarPlot that specifies whether interpolation points of an approximant to a function should be displayed.
OrderStarKind is an option to OrderStarPlot that specifies the type of order star to be displayed.
OrderStarLegend is an option to OrderStarPlot that specifies whether to display the legend of symbols used to represent zeros, poles and interpolation points.
OrderStarPoles is an option to OrderStarPlot that specifies whether poles of an approximant and the function to be approximated should be displayed.
OrderStarSymbolSize is an option to OrderStarPlot that specifies the size of the symbols used to represent poles, zeros and interpolation points.
OrderStarSymbolThickness is an option to OrderStarPlot that specifies the thickness of the outline of the symbols used to represent interpolation points, poles and zeros.
OrderStarZeros is an option to OrderStarPlot that specifies whether zeros of an approximant and the function to be approximated should be displayed.
