Using This Guide

Expected Background

This guide assumes that you already have background knowledge in the

subject of curve fitting data. If you do not yet have this background, then you

should read a standard curve fitting text, some of which are listed in “Selected

Bibliography” on page 3-75.

When learning to use the toolbox, you should start with Chapter 1, “Getting

Started with the Curve Fitting Toolbox,” which illustrates the major toolbox

features by fitting census data to several equations and then evaluating the

best fit. More detailed information about the features discussed in this chapter

is available elsewhere in the guide, and you should browse the documentation

according to your needs.

How This Guide Is Organized

The organization of this guide is described below.

Chapter Description

Getting Started with the

Curve Fitting Toolbox

Describes a particular example in detail to help

you get started with the toolbox.

Importing, Viewing, and

Preprocessing Data

Describes how to import, view, and smooth

data sets, and how to exclude one or more data

points in a data set from subsequent fits.

Fitting Data Describes how to fit data using library or

custom equations, a smoothing spline, or an

interpolant. Several detailed examples are

included as well.

Function Reference Describes all toolbox functions in detail.
