Parameters

mat	matrix from which column will be extracted
j	index

Returns

column of the given matrix at the given index

find()

int GlassBR.Interpolation.find ( ArrayList< Double > arr, double v ) throws Exception, IOException

static

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()

static

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 GlassBR.Interpolation.interpZ ( String filename, double x, double y ) throws Exception, FileNotFoundException, IOException

static

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()
