Constructor Details

FieldBilinearInterpolatingFunction

public FieldBilinearInterpolatingFunction(T[] xVal,
 T[] yVal,
 T[][] fVal)
                                   throws MathIllegalArgumentException

Simple constructor.

Parameters:

xVal - All the x-coordinates of the interpolation points, sorted in increasing order.

yVal - All the y-coordinates of the interpolation points, sorted in increasing order.

fVal - The values of the interpolation points on all the grid knots: fVal[i][j] = f(xVal[i], yVal[j]).

Throws:

MathIllegalArgumentException - if grid size is smaller than 2 or if the grid is not sorted in strict increasing order
