This section provides an overview of some of the MATLAB basic data analysis capabilities in the form of a case study. The examples that follow work with a collection of census data, using MATLAB functions to experiment with fitting curves to the data:

This section also tells you how to use the Basic Fitting interface to perform curve fitting tasks.

**Loading the Data**

The file `census.mat`

contains U.S. population data for the years 1790 through 1990. Load it into MATLAB:

Your workspace now contains two new variables, `cdate`

and `pop`

:

`cdate`

is a column vector containing the years from 1790 to 1990 in increments of 10.`pop`

is a column vector with the U.S. population figures that correspond to the years in`cdate`

.
