public class DataTables2D

extends Object

Class DataTables2D provides static methods to create data tables from "functions" of type Function.OneArg.

The data tables may be used for numerical processing or for plotting with the plot tools.

See also the makeTable methods in BaseParser.

DataTables2D()

Method Summary

static Point2D[][]	makeTable(Function.OneArg[] f, double endpointA, double endpointB, int divisions) Make a Point2D array of arrays of pairs (x, f[i](x)) where i ranges over the valid indices for the function array f and where x is sampled on the given interval divided into the number of divisions.
static Point2D[][]	makeTable(Function.OneArg[] f, XInterval limits, int divisions) Make a Point2D array of arrays of pairs (x,f[i](x)) where i ranges over the valid indices for the function array f and where x is sampled on the given interval divided into the number of divisions.
static Point2D[]	makeTable(Function.OneArg f, double endpointA, double endpointB, int divisions) Make a Point2D array of pairs (x,f(x)) where x is sampled on the given interval divided into the given number of divisions.
static Point2D[]	makeTable(Function.OneArg f, XInterval limits, int divisions) Make a Point2D array of pairs (x,f(x)) where x is sampled on the given interval divided into the given number of divisions.

Method Detail

makeTable

public static Point2D[] makeTable(Function.OneArg f,
                                  XInterval limits,
                                  int divisions)

Make a Point2D array of pairs (x,f(x)) where x is sampled on the given interval divided into the given number of divisions.

If the given function or the given limits is null, returns null.

If divisions is less than 1, it will be set to 1. The size of the output array will be (divisions+1).

Parameters:

f - the function of one argument to evaluate

limits - the interval on which to evaluate

divisions - the number of subdivisions of the interval

Returns:

the array of (divisions+1) Point2D (x,f(x)) pairs

makeTable

public static Point2D[] makeTable(Function.OneArg f,
                                  double endpointA,
                                  double endpointB,
                                  int divisions)

Make a Point2D array of pairs (x,f(x)) where x is sampled on the given interval divided into the given number of divisions.

If the given function is null, returns null.

If divisions is less than 1, it will be set to 1. The size of the output array will be (divisions+1).

Parameters:

f - the function of one argument to evaluate

endpointA - an endpoint of the interval

endpointB - an endpoint of the interval

divisions - the number of subdivisions of the interval

Returns:

the array of (divisions + 1) Point2D (x,f(x)) pairs

makeTable

public static Point2D[][] makeTable(Function.OneArg[] f,
                                    XInterval limits,
                                    int divisions)

Make a Point2D array of arrays of pairs (x,f[i](x)) where i ranges over the valid indices for the function array f and where x is sampled on the given interval divided into the number of divisions.

If the given function array or the given limits is null, returns null.

If a particular function in the function array is null, the corresponding row of the return array will also be null.

If divisions is less than 1, it will be set to 1. The size of the output array will be (f.length)*(divisions+1).

Parameters:

f - the array of functions of one argument to evaluate

limits - the interval on which to evaluate

divisions - the number of subdivisions of the interval

Returns:

the array of arrays of Point2D pairs

makeTable

public static Point2D[][] makeTable(Function.OneArg[] f,
                                    double endpointA,
                                    double endpointB,
                                    int divisions)

Make a Point2D array of arrays of pairs (x, f[i](x)) where i ranges over the valid indices for the function array f and where x is sampled on the given interval divided into the number of divisions.

If the given function array is null, returns null.

If a particular function in the function array is null, the corresponding row of the return array will also be null.

If divisions is less than 1, it will be set to 1. The size of the output array will be (f.length)*(divisions+1).

Parameters:

f - the array of functions of one argument to evaluate

endpointA - an endpoint of the interval

endpointB - an endpoint of the interval

divisions - the number of subdivisions of the interval

Returns:

the array of arrays of Point2D pairs
