Controlling Command Window Input and Output

The format Function

The format function controls the numeric format of the values displayed. The function affects only how numbers are displayed, not how MATLAB software computes or saves them. Here are the different formats, together with the resulting output produced from a vector x with components of different magnitudes. Read More

Working with Matrices in Matlab

Generating Matrices

MATLAB software provides four functions that generate basic matrices. Read More

Matlab Expressions

Variables

Like most other programming languages, the MATLAB language provides mathematical expressions, but unlike most programming languages, these expressions involve entire matrices. 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
