Function Documentation

extractColumn()

python.Interpolation.extractColumn	(		mat,
			j )

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()

python.Interpolation.find	(		arr,
			v )

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()

python.Interpolation.interpY	(		filename,
			x,
			z )

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()

python.Interpolation.interpZ	(		filename,
			x,
			y )

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()

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

Performs linear interpolation.

Parameters

x_1	lower x-coordinate
y_1	lower y-coordinate
x_2	upper x-coordinate
y_2	upper y-coordinate
x	x-coordinate to interpolate at

Returns

y value interpolated at given x value
