extractColumn()

List< double > Interpolation.extractColumn ( List< List< double > > mat, int j )

inlinestatic

Extracts a column from a 2D matrix.

Parameters

mat	matrix from which column will be extracted
j	index

Returns

column of the given matrix at the given index

find()

int Interpolation.find ( List< double > arr, double v )

inlinestatic

Finds the array index for a value closest to the given value.

Parameters

arr	array in which value should be found
v	value whose index will be found

Returns

index of given value in given array

interpY()

double Interpolation.interpY ( string filename, double x, double z )

inlinestatic

Linearly interpolates a y value at given x and z values.

Parameters

filename	name of file with x y and z data
x	x-coordinate to interpolate at
z	z-coordinate to interpolate at

Returns

y value interpolated at given x and z values

interpZ()

double Interpolation.interpZ ( string filename, double x, double y )

inlinestatic

Linearly interpolates a z value at given x and y values.

Parameters

filename	name of file with x y and z data
x	x-coordinate to interpolate at
y	y-coordinate to interpolate at

Returns

z value interpolated at given x and y values

lin_interp()

double Interpolation.lin_interp ( double x_1, double y_1, double x_2, double y_2, double x )

inlinestatic

Performs linear interpolation.

Parameters
