Scoping Classes with Packages
Package Folders
Packages are special folders that can contain class folders, function and class definition files, and other packages. Packages define a scope (sometimes called a namespace) for the contents of the package folder. This means function and class names need to be unique only within the package. Using a package provides a means to organize classes and functions and to select names for these components that other packages can reuse. Read More

Localize minima and maxima of functions
Let us try to find the local minima and maxima for the function func(x). The interval of interest is [-6 0]. The algorithms are iterative. There are 2 methods to use. The first one decides x in a given interval, and the second one looks for x around an initial guess. To decide the maxima we are looking for an x that minimizes the negative function: -func(x).

Analysis of Functions, Interpolation, Curve Fitting, Integrals and Differential Equations
In this tutorial we will deal with analysis of functions, interpolation, curve fitting, integrals and differential equations. Firstly, we will need to use polynomials and therefore we have to be familiar with the representation of these. A general polynomial looks like: p(x)=anxn + an-1xn-1 +……….+ a1x + a0 and is represented by a vector in Matlab:
p=[ an an-1 ....... a1 a0 ] Read More

path Get/set search path.
PATH, by itself, prettyprints MATLAB’s current search path. The
initial search path list is set by PATHDEF, and is perhaps
individualized by STARTUP. Read More
What Is MATLAB?
MATLAB is a high-performance language for technical computing. It ntegrates computation, visualization, and programming in an easy-to-use nvironment where problems and solutions are expressed in familiar athematical notation. Typical uses include: Read More
Manipulating Matrices
Matrices and Magic Squares
In MATLAB, a matrix is a rectangular array of numbers. Special meaning is sometimes attached to 1-by-1 matrices, which are scalars, and to matrices with only one row or column, which are vectors. MATLAB has other ways of storing both numeric and nonnumeric data, but in the beginning, it is usually best to think of everything as a matrix. The operations in MATLAB are designed to be as natural as possible. Where other programming languages work with numbers one at a time, MATLAB allows you to work with entire matrices quickly and easily. A good example matrix, used throughout this book, appears in the Renaissance engraving Melancholia I by the German artist and amateur mathematician Albrecht Dürer. Read More
