MATH2D SPL Directory

 

The Math2D directory contains functions for analysis of tables and arrays (2D), as well as plotting and spinning XYZ data. The following functions are included:

 

GRADIENT

Calculates the 2D derivative of an array.

IGRID

Grids XYZ data using the inverse distance method.

INTERP2

Performs 2 dimensional linear interpolation.

PEAKS

Generates a Gaussian function of two variables, z = f(x, y).

SGRID

Grids XYZ data using spline interpolation.

SPIN

Spins a 3D plot.

SPLINE2

Performs two-dimensional cubic spline fitting.

XYZ

Creates a 3D XYZ plot.
