The find Function

matlabtutorials — Sat, 08 May 2010 23:52:07 +0000

The find function determines the indices of array elements that meet a given logical
condition. In its simplest form, find returns a column vector of indices. Transpose that
vector to obtain a row vector of indices. For example, Read More

Manipulating Matrices

matlabtutorials — Thu, 13 Mar 2008 00:10:37 +0000

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
